##### 2. Question

A man can row 6 kmph in still water. When the river is running at 1.2 kmph, it takes him 1 hour to row to a place and black. What is the total distance traveled by the man?

CorrectM = 6

S = 1.2

DS = 7.2

US = 4.8

x/7.2 + x/4.8 = 1

x = 2.88

D = 2.88 * 2 = 5.76IncorrectM = 6

S = 1.2

DS = 7.2

US = 4.8

x/7.2 + x/4.8 = 1

x = 2.88

D = 2.88 * 2 = 5.76 - Question 3 of 50
##### 3. Question

If a + b + c = 0 and abc ≠ 0, then [X

^{a3 / abc}][X^{b3 / abc}][X^{c3 / abc}] equalsCorrectX

^{a3 / abc}* X^{b3 / abc}* X^{c3 / abc = X}^{(a3 + b3 + c3) / abc}

As a + b + c = 0, (a^{3}+ b^{3}+ c^{3}) / abc = 3

The given expression equals X^{3}IncorrectX

^{a3 / abc}* X^{b3 / abc}* X^{c3 / abc = X}^{(a3 + b3 + c3) / abc}

As a + b + c = 0, (a^{3}+ b^{3}+ c^{3}) / abc = 3

The given expression equals X^{3} - Question 4 of 50

##### 5. Question

If x = √196 + √200, then x/2 + 2/x is?

Correctx = 14 + 10√2

x/2 = 7 + 5√2

2/x = (7 – 5√2) / (7 + 5√2)(7 – 5√2) = 5√2 – 7

x/2 + 2/x = 10√2 = 2√50Incorrectx = 14 + 10√2

x/2 = 7 + 5√2

2/x = (7 – 5√2) / (7 + 5√2)(7 – 5√2) = 5√2 – 7

x/2 + 2/x = 10√2 = 2√50 - Question 6 of 50
##### 6. Question

CorrectC.P. of 50 kg wheat = (30 * 11.50 + 20 * 14.25) = Rs. 630.

S.P. of 50 kg wheat = 130% of Rs. 630 = 130/100 * 630 = Rs. 819.

S.P. per kg = 819/50 = Rs. 16.38 = 16.30.IncorrectC.P. of 50 kg wheat = (30 * 11.50 + 20 * 14.25) = Rs. 630.

S.P. of 50 kg wheat = 130% of Rs. 630 = 130/100 * 630 = Rs. 819.

S.P. per kg = 819/50 = Rs. 16.38 = 16.30. - Question 11 of 50

A man is 24 years older than his son. In two years, his age will be twice the age of his son. The present age of the son is:

CorrectLet the son’s present age be x years.

Then, man’s present age = (x + 24) years.

(x + 24) + 2 = 2(x + 2) x + 26 = 2x + 4 => x = 22.IncorrectLet the son’s present age be x years.

Then, man’s present age = (x + 24) years.

(x + 24) + 2 = 2(x + 2) x + 26 = 2x + 4 => x = 22. - Question 13 of 50
##### 13. Question

A fair price shopkeeper takes 10% profit on his goods. He lost 20% goods during theft. His loss percent is:

CorrectSuppose he has 100 items. Let C.P. of each item be Re. 1.

Total cost = Rs. 100. Number of items left after theft = 80.

S.P. of each item = Rs. 1.10

Total sale = 1.10 * 80 = Rs. 88

Hence, loss % = 12/100 * 100 = 12%IncorrectSuppose he has 100 items. Let C.P. of each item be Re. 1.

Total cost = Rs. 100. Number of items left after theft = 80.

S.P. of each item = Rs. 1.10

CorrectA+B+C = 1500

A = 1/3(B+C); B = 2/3(A+C)

A/(B+C) = 1/3

A = 1/4 * 1500 => 375IncorrectA+B+C = 1500

A = 1/3(B+C); B = 2/3(A+C)

A/(B+C) = 1/3

A = 1/4 * 1500 => 375 - Question 16 of 50

##### 29. Question

Ten years ago, the age of Anand was one-third the age of Bala at that time. The present age of Bala is 12 years more than the present age of Anand. Find the present age of Anand?

CorrectLet the present ages of Anand and Bala be ‘a’ and ‘b’ respectively.

a – 10 = 1/3 (b – 10) — (1)

b = a + 12

Substituting b = a + 12 in first equation,

a – 10 = 1/3 (a + 2) => 3a – 30 = a + 2

=> 2a = 32 => a = 16.IncorrectLet the present ages of Anand and Bala be ‘a’ and ‘b’ respectively.

a – 10 = 1/3 (b – 10) — (1)

b = a + 12

Substituting b = a + 12 in first equation,

a – 10 = 1/3 (a + 2) => 3a – 30 = a + 2

##### 32. Question

An amount of Rs. 3000 becomes Rs. 3600 in four years at simple interest. If the rate of interest was 1% more, then what was be the total amount?

CorrectA = P(1 + TR/100)

=> 3600 = 3000[1 + (4 * R)/100] => R = 5%

Now R = 6%

=> A = 3000[1 + (4 * 6)/100] = Rs. 3720.IncorrectA = P(1 + TR/100)

=> 3600 = 3000[1 + (4 * R)/100] => R = 5%

Now R = 6%

=> A = 3000[1 + (4 * 6)/100] = Rs. 3720. - Question 33 of 50

##### 35. Question

(830 + ? * 3 * 14 / 100) – (830 * 14 * 3 / 100) = 20.16

Correct(830 + ? * 3 * 14 / 100) – (830 * 14 * 3 / 100) = 20.16

=> 830 + ? * 42 – 830 * 42 = 2018

=> ? * 42 = 2018 + 830 * 42 – 830

=> ? * 42 = 42 * 48 + 830 * 42 – 830

=> ? = 48 + 830 – (830 / 42)

=> ? = 48 + 830 – 19.76

=> ? = 858.24Incorrect(830 + ? * 3 * 14 / 100) – (830 * 14 * 3 / 100) = 20.16

=> 830 + ? * 42 – 830 * 42 = 2018

=> ? * 42 = 2018 + 830 * 42 – 830

=> ? * 42 = 42 * 48 + 830 * 42 – 830

=> ? = 48 + 830 – (830 / 42)

=> ? = 48 + 830 – 19.76

##### 36. Question

The compound interest accrued on an amount of Rs.44000 at the end of two years is Rs.1193.60. What would be the simple interest accrued on the same amount at the same rate in the same period?

CorrectLet the rate of interest be R% p.a.

4400{[1 + R/100]^{2}– 1} = 11193.60

[1 + R/100]^{2}= (44000 + 11193.60)/44000

[1 + R/100]^{2}= 1 + 2544/1000 = 1 + 159/625

[1 + R/100]^{2}= 784/625 = (28/25)^{2}

1 + R/100 = 28/25

R/100 = 3/25

Therefore R = 12 SI on Rs.44000 at 12% p.a. for two years = 44000(2)(12)/100

=Rs.10560IncorrectLet the rate of interest be R% p.a.

4400{[1 + R/100]^{2}– 1} = 11193.60

[1 + R/100]^{2}= (44000 + 11193.60)/44000

[1 + R/100]^{2}= 1 + 2544/1000 = 1 + 159/625

[1 + R/100]^{2}= 784/625 = (28/25)^{2}

1 + R/100 = 28/25

R/100 = 3/25

Therefore R = 12 SI on Rs.44000 at 12% p.a. for two years = 44000(2)(12)/100

=Rs.10560 - Question 37 of 50
##### 37. Question

A two-digit number is such that the product of the digits is 8. When 18 is added to the number, then the digits are reversed. The number is:

CorrectLet the ten’s and unit’s digit be x and 8/x respectively.

Then,

(10x + 8/x) + 18 = 10 * 8/x + x

9x^{2}+ 18x – 72 = 0

x^{2}+ 2x – 8 = 0

(x + 4)(x – 2) = 0

x = 2

So, ten’s digit = 2 and unit’s digit = 4.

Hence, required number = 24.IncorrectLet the ten’s and unit’s digit be x and 8/x respectively.

Then,

(10x + 8/x) + 18 = 10 * 8/x + x

9x^{2}+ 18x – 72 = 0

x^{2}+ 2x – 8 = 0

(x + 4)(x – 2) = 0

x = 2

So, ten’s digit = 2 and unit’s digit = 4.

Hence, required number = 24. - Question 38 of 50

What is the least number to be subtracted from 696 to make it a perfect square?

CorrectThe numbers less than 696 and are squares of certain numbers are 676, 625.

The least number that should be subtracted from 696 to make it perfect square = 696 – 676 = 20.IncorrectThe numbers less than 696 and are squares of certain numbers are 676, 625.

##### 41. Question

A 25 cm wide path is to be made around a circular garden having a diameter of 4 meters. Approximate area of the path is square meters is

CorrectArea of the path = Area of the outer circle – Area of the inner circle = ∏{4/2 + 25/100}

^{2}– ∏[4/2]^{2}

= ∏[2.25^{2}– 2^{2}] = ∏(0.25)(4.25) { (a^{2}– b^{2}= (a – b)(a + b) }

Two persons start running simultaneously around a circular track of length 300 m from the same point at speeds of 15 km/hr and 25 km/hr. When will they meet for the first time any where on the track if they are moving in opposite directions?

CorrectTime taken to meet for the first time anywhere on the track

= length of the track / relative speed

= 300 / (15 + 25)5/18 = 300* 18 / 40 * 5 = 27 seconds.IncorrectTime taken to meet for the first time anywhere on the track

##### 45. Question

Two pipes A and B together can fill a cistern in 4 hours. Had they been opened separately, then B would have taken 6 hours more than A to fill cistern. How much time will be taken by A to fill the cistern separately?

CorrectLet the cistern be filled by pipe A alone in x hours.

Then, pipe B will fill it in (x + 6) hours.

1/x + 1/(x + 6) = 1/4

x^{2}– 2x – 24 = 0

(x – 6)(x + 4) = 0 => x = 6.IncorrectLet the cistern be filled by pipe A alone in x hours.

Then, pipe B will fill it in (x + 6) hours.

1/x + 1/(x + 6) = 1/4

x^{2}– 2x – 24 = 0

(x – 6)(x + 4) = 0 => x = 6. - Question 46 of 50

##### 48. Question

The average weight of a group of persons increased from 48 kg to 51 kg, when two persons weighing 78 kg and 93 kg join the group. Find the initial number of members in the group?

CorrectLet the initial number of members in the group be n.

Initial total weight of all the members in the group = n(48)

From the data,

48n + 78 + 93 = 51(n + 2) => 51n – 48n = 69 => n = 23

Therefore there were 23 members in the group initially.IncorrectLet the initial number of members in the group be n.
