Solutions:

1. Side of the first square is 4cm. Area of the first square is 16 sq.cm. Area of the second square will be 32 sq.cm. So, side of the second square will be 4√2 cm. So, diagonal will be 8 cm in length. Option a.

2. The length of the body diagonal will be the maximum length and so, √104 or 2√26 is the answer. Option c.

3. Only X is 4.7, only Y is 4.6 and only Z is 2.6. So, people who read at least one newspaper would be 17.4 lakh. Option c.

4. The total is 11.9. Option b.

5. 30% is 12750. So, overall will be 42500. Option a.

6. {25x + 900}*1.1 = 30*(x + 30)

27.5x + 990 = 30x + 900

x = 36. Option a.

7. 7/8 of the girls and ¾ of the boys passed. Total of 64 students passed. Let boys be x.

7(80 – x)/8 + 3x/4 = 64

x = 48. Option b.

8. (120 + x)/(300 + x) = ½, x = 60. Option b.

9. Option d.

10. Option b.

11. It’s the same ratio and so, 4 years. Option c.

12. At the start, J + B = 4T, T + B = 3J.

At the end, J’ + B’ = 3T’, T’ + B’ = 2J’

T/(J + B + T) = 1/5. Option d.

13. J – T = 4T – 3J

4J = 5T, B = 2.2J

J’ – T’ = 3T’ – 2J’

3J’ = 4T’, B’ = 1.25J’

But, B – B’ = 200

2.2J – 1.25J’ = 200

220J/100 – 125J’/100 = 200

220J – 125J’ = 20000

44J – 25J’ = 4000

Also, J + B + T = J’ + B’ + T’

4J = 3J’

J’ = 500, J = 375

B’ = 625, B = 825

T’ = 375, T = 300

Total money = 1500, J won 125. So, J won 1/12. Option a.

14. Option c.

15. Let a = -1, b = -2 and c = 1. Statement I and III are violated. Option b has to be correct.
