Science students of school A is 25% more than science students of school B. 28.57 percent of total students in school B study in Science department.

Total students in art stream in A is what percent more than total students in science stream in B?

Correct

Answer – 4) 100%
Explanation
The total number of students in school A is 960.
So the remaining students in School B are 840.
Art students in school A is 50 % of the total number of students in school A = 480
28.57 percent of total students in school B study in Science department.
= 2/7 of 840 = 240
Science students of school A is 25% more than science students of school B.
= 300
The ratio of Commerce students in school A and B is 9:8
9x = 180
X= 20
8x = 160

Incorrect

Answer – 4) 100%

Amit can do a piece of work in 40 days, but Bhanu can do the same work in 10 more days, than Amit. When working alone, Amit and Bhanu both started the work together but Amit left after some days and Bhanu finished the remaining work in 55 days with half of his efficiency but he did the work with Amit with his complete efficiency. For how many days they had worked together ?

Correct

Answer – 4) 10
Explanation –
Let the total work is LCM of 40 and 50 = 200
Per day work by Amit = 200/40 = 5
Per day work by Bhanu = 200/50 = 4
Since Bhanu alone work for 55days with half efficiency = 55 × ½ ×4 = 110
Work done by Amit and Bhanu together = 200-110 = 90
Time take to work together by them = 90/(5+4) = 10

Incorrect

Answer – 4) 10
Explanation –
Let the total work is LCM of 40 and 50 = 200
Per day work by Amit = 200/40 = 5
Per day work by Bhanu = 200/50 = 4
Since Bhanu alone work for 55days with half efficiency = 55 × ½ ×4 = 110
