##### 2. Question

Two tests had the same maximum mark. The pass percentages in the first and the second test were 40% and 45% respectively. A candidate scored 216 marks in the second test and failed by 36 marks in that test. Find the pass mark in the first test?

CorrectLet the maximum mark in each test be M.

The candidate failed by 36 marks in the second test.

pass mark in the second test = 216 + 36 = 252

45/100 M = 252

Pass mark in the first test = 40/100 M = 40/45 * 252 = 224.IncorrectLet the maximum mark in each test be M.

The candidate failed by 36 marks in the second test.

pass mark in the second test = 216 + 36 = 252

45/100 M = 252

Pass mark in the first test = 40/100 M = 40/45 * 252 = 224. - Question 3 of 50
##### 3. Question

In a 1000 m race, A beats B by 50 m and B beats C by 100 m. In the same race, by how many meters does A beat C?

CorrectBy the time A covers 1000 m, B covers (1000 – 50) = 950 m.

By the time B covers 1000 m, C covers (1000 – 100) = 900 m.

So, the ratio of speeds of A and C =

1000/950 * 1000/900 = 1000/855 So, by the time A covers 1000 m, C covers 855 m.

So in 1000 m race A beats C by 1000 – 855 = 145 m.IncorrectBy the time A covers 1000 m, B covers (1000 – 50) = 950 m.

By the time B covers 1000 m, C covers (1000 – 100) = 900 m.

So, the ratio of speeds of A and C =

1000/950 * 1000/900 = 1000/855 So, by the time A covers 1000 m, C covers 855 m.

So in 1000 m race A beats C by 1000 – 855 = 145 m. - Question 4 of 50

##### 5. Question

A and B can do a work in 8 days, B and C can do the same work in 12 days. A, B and C together can finish it in 6 days. A and C together will do it in?

Correct(A + B + C)’s 1 day work = 1/6;

(A + B)’s 1 day work = 1/8

(B + C)’s 1 day work = 1/12

(A + C)’s 1 day work = (2 * 1/6) – (1/8 + 1/12)

= (1/3 – 5/24) = 1/8

So, A and C together will do the work in 8 days.Incorrect(A + B + C)’s 1 day work = 1/6;

(A + B)’s 1 day work = 1/8

(B + C)’s 1 day work = 1/12

(A + C)’s 1 day work = (2 * 1/6) – (1/8 + 1/12)

= (1/3 – 5/24) = 1/8

So, A and C together will do the work in 8 days. - Question 6 of 50

##### 39. Question

Mohit sold an article for Rs. 18000. Had he offered a discount of 10% on the selling price, he would have earned a profit of 8%. What is the cost price of the article?

CorrectLet the CP be Rs. x.

Had he offered 10% discount, profit = 8%

Profit = 8/100 x and hence his SP = x + 8/100 x = Rs. 1.08x = 18000 – 10/100(18000) = 18000 – 1800 = Rs. 16200

=> 1.08x = 16200

=> x = 15000IncorrectLet the CP be Rs. x.

Had he offered 10% discount, profit = 8%

Profit = 8/100 x and hence his SP = x + 8/100 x = Rs. 1.08x = 18000 – 10/100(18000) = 18000 – 1800 = Rs. 16200

=> 1.08x = 16200
