The average monthly income of P and Q is Rs. 5050. The average monthly income of Q and R is 6250 and the average monthly income of P and R is Rs. 5200. The monthly income of P is:

CorrectLet P, Q and R represent their respective monthly incomes. Then, we have:

P + Q = (5050 * 2) = 10100 — (i)

Q + R = (6250 * 2) = 12500 — (ii)

P + R = (5200 * 2) = 10400 — (iii)

Adding (i), (ii) and (iii), we get:

2(P + Q + R) = 33000 = P + Q + R = 16500 — (iv)

Subtracting (ii) from (iv), we get, P = 4000.

P’s monthly income = Rs. 4000.IncorrectLet P, Q and R represent their respective monthly incomes. Then, we have:

P + Q = (5050 * 2) = 10100 — (i)

Q + R = (6250 * 2) = 12500 — (ii)

P + R = (5200 * 2) = 10400 — (iii)

Adding (i), (ii) and (iii), we get:

2(P + Q + R) = 33000 = P + Q + R = 16500 — (iv)

##### 28. Question

The area of the square formed on the diagonal of a rectangle as its side is 108 1/3 % more than the area of the rectangle. If the perimeter of the rectangle is 28 units, find the difference between the sides of the rectangle?

CorrectLet the sides of the rectangle be l and b respectively.

From the given data,

(√l^{2}+ b^{2}) = (1 + 108 1/3 %)lb

=> l^{2}+ b^{2}= (1 + 325/3 * 1/100)lb

= (1 + 13/12)lb

= 25/12 lb

=> (l^{2}+ b^{2})/lb = 25/12

12(l^{2}+ b^{2}) = 25lb

Adding 24lb on both sides

12l^{2}+ 12b^{2}+ 24lb = 49lb

12(l^{2}+ b^{2}+ 2lb) = 49lb

but 2(l + b) = 28 => l + b = 14

12(l + b)^{2}= 49lb

=> 12(14)^{2}= 49lb

=> lb = 48

Since l + b = 14, l = 8 and b = 6

l – b = 8 – 6 = 2m.IncorrectLet the sides of the rectangle be l and b respectively.

From the given data,

(√l^{2}+ b^{2}) = (1 + 108 1/3 %)lb

=> l^{2}+ b^{2}= (1 + 325/3 * 1/100)lb

= (1 + 13/12)lb

= 25/12 lb

=> (l^{2}+ b^{2})/lb = 25/12

12(l^{2}+ b^{2}) = 25lb

Adding 24lb on both sides

12l^{2}+ 12b^{2}+ 24lb = 49lb

12(l^{2}+ b^{2}+ 2lb) = 49lb

but 2(l + b) = 28 => l + b = 14

12(l + b)^{2}= 49lb

=> 12(14)^{2}= 49lb

=> lb = 48

Since l + b = 14, l = 8 and b = 6

l – b = 8 – 6 = 2m. - Question 29 of 50
##### 29. Question

If 10% of x = 20% of y, then x:y is equal to:

x/y = 10/5 = 2/1

x:y = 2:1.Incorrect10% of x = 20% of y

10x/100 = 20y/100 => x/10 = y/5

x/y = 10/5 = 2/1

x:y = 2:1. - Question 30 of 50

##### 40. Question

The sum of the squares of two consecutive positive integers exceeds their product by 91. Find the integers?

CorrectLet the two consecutive positive integers be x and x + 1

x^{2}+ (x + 1)^{2}– x(x + 1) = 91

x^{2}+ x – 90 = 0

(x + 10)(x – 9) = 0 => x = -10 or 9.

As x is positive x = 9

Hence the two consecutive positive integers are 9 and 10.IncorrectLet the two consecutive positive integers be x and x + 1

##### 44. Question

In a fort, there are 1200 soldiers. If each soldier consumes 3 kg per day, the provisions available in the fort will last for 30 days. If some more soldiers join, the provisions available will last for 25 days given each soldier consumes 2.5 kg per day. Find the number of soldiers joining the fort in that case?

CorrectAssume X soldiers join the fort. 1200 soldiers have provision for 1200(days for which provisions last them)(rate of consumption of each soldier)

= 1200(30)(3) kg

Also provisions available for (1200 + x) soldiers is (1200 + x)(25)(2.5) kg

As the same provisions are available

=> 1200(30)(3) = (1200 + x)(25)(2.5)

x = [1200(30)(3)]/[(25)(2.5)] – 1200

x = 528IncorrectAssume X soldiers join the fort. 1200 soldiers have provision for 1200(days for which provisions last them)(rate of consumption of each soldier)

= 1200(30)(3) kg

As the same provisions are available

=> 1200(30)(3) = (1200 + x)(25)(2.5)

x = [1200(30)(3)]/[(25)(2.5)] – 1200

##### 46. Question

Two persons A and B can complete a piece of work in 30 days and 45 days respectively. If they work together, what part of the work will be completed in 3 days?

CorrectA’s one day’s work = 1/30

B’s one day’s work = 1/45

(A + B)’s one day’s work = 1/30 + 1/45 = 1/18

The part of the work completed in 3 days = 3 (1/18) = 1/6.IncorrectA’s one day’s work = 1/30

B’s one day’s work = 1/45

(A + B)’s one day’s work = 1/30 + 1/45 = 1/18

The part of the work completed in 3 days = 3 (1/18) = 1/6. - Question 47 of 50
