1. Let the total task be 100 units. So, Ram does 60 units in 15 days. So, Ram does 4 units per day. Rahim does 2 units per day and Rachel does 1 unit per day. So, together they do 7 units per day. As 40 units are remaining they will take another 40/7 days to finish the work. Option c.

2. Let the total work be 168 units. So, A does 8 units per day and B does 7 units per day. B works alone for 9 days and so, does 63 units. So, they together do 105 units and so, should take 7 days to finish those. Option b.

3. Let the selling price of 75 articles be 75x. So, selling price of 100 articles is 100x. Profit is equal to 75x in the second case. So, cost price is equal to 25x in the second case. So, profit percentage will be 75x/25x * 100 = 300%. Option c.

4. A covers 100 m in time t seconds, B covers 80 m in time (t + 5) seconds. A covers 100 m in the same time as B covers 60 m. So, we can compare the speeds of A and B using the two bits of information.

Speed of A = 100/t

Speed of B = 80/(t + 5)

Speed of A : Speed of B = Distance covered by A : Distance covered by B = 100 : 60 or 5 : 3

(100/t)/(80/(t + 5)) = 5/3

On solving, we get t = 15 seconds. So, A will cover 200 m in 2t or 30 seconds. Option c.

5. Initial surface area is 96. Final surface area is 384. So, the increase is by 300%. Option b.

6. 2G should be 16 and so, G can only be 8. Option a.

7. Let the total work be 60 units. Amit does 5 units per day and Sagar does 4 units per day. So, together they would finish 36 units in 4 days and so, 40% of the work is left. Option c.

8. 60x + 40x – x^2 = 2400 – 2109

x^2 – 100x + 291 = 0

So, x = 3 or x = 97. But, x cannot be greater than 60 and so, x = 3. Option b.

9. ½ * (5c1*3c1/8c2 + 4c1*5c1/9c2) = 275/504. Option a.

10. Option b using equal intercept theorem.

11. 105/360 = 7/24 = approximately 30%. Option b.

12. 30/120 = 25%. Option c.

13. 30 degrees -> 45 degrees. So, 15 degrees need to be removed from sleeping. So, sleeping decreased by 15 degrees on 120 degrees or by 12.5%. Option b.

14. 60 degrees or 1/6th of the day. So, 4 hours. Option c.

15. 2/3 * 45 spent on other subjects. So, 30 degrees on 360 degrees or 1/12th of 24 hours or 2 hours. Option b.
