Answer: Option C
Explanation:
To reach the winning post A will have to cover a distance of (500 – 140)m, i.e., 360 m.
While A covers 3 m, B covers 4 m.
| While A covers 360 m, B covers | 4 | x 360 | m | = 480 m. | |
| 3 |
Thus, when A reaches the winning post, B covers 480 m and therefore remains 20 m behind.
A wins by 20 m.

Answer: Option D
Explanation:
(4 + 5 + 2) – (1 + 6 + 3) = 1, not divisible by 11.
(2 + 6 + 4) – (4 + 5 + 2) = 1, not divisible by 11.
(4 + 6 + 1) – (2 + 5 + 3) = 1, not divisible by 11.
(4 + 6 + 1) – (2 + 5 + 4) = 0, So, 415624 is divisible by 11.

Answer: Option A
Explanation:
Let investment in 12% stock be Rs. x.
Then, investment in 15% stock = Rs. (12000 – x).
| 12 | x x + | 15 | x (12000 – x) = 1360. | |
| 120 | 125 |
| x | + | 3 | (12000 – x) = 1360. | |
| 10 | 25 |
5x + 72000 – 6x = 1360 x 50
x = 4000.

| Since, | 70 | > | 65 | > | 63 | > | 62 | , so | 7 | > | 13 | > | 63 | > | 31 |
| 80 | 80 | 80 | 80 | 8 | 16 | 80 | 40 |
| So, | 7 | is the largest. |
