Answer: Option E
Explanation:
| Given Exp. = | 800 | x | 1296 | = 450 |
| 64 | 36 |
A. Rs 230
B. Rs 232
C. Rs 600
D. Rs 832
Explanation:
S.I = Rs (6000 × 5/100 × 2) = Rs 600
C.I = Rs [5000 × (1 + 8/100)2 – 5000]
= Rs (5000 × 27/25 × 27/25 – 5000)
= Rs(5832 – 5000)
= Rs 832
(C.I) – (S.I) = Rs (832 – 600) = Rs 232

Answer: Option B
Explanation:
| Work done = | 5 |
| 8 |
| Balance work = | 1 – | 5 | = | 3 | ||
| 8 | 8 |
Let the required number of days be x.
| Then, | 5 | : | 3 | = :: 10 : x | 5 | x x = | 3 | x 10 | |
| 8 | 8 | 8 | 8 |
| x = | 3 | x 10 x | 8 | ||
| 8 | 5 |
x = 6.
[B].
[C].
[D].
Answer: Option C
Explanation:
| (A + B)’s 1 day’s work = | 1 | + | 1 | = | 1 | . | ||
| 15 | 10 | 6 |
| Work done by A and B in 2 days = | 1 | x 2 | = | 1 | . | ||
| 6 | 3 |
| Remaining work = | 1 – | 1 | = | 2 | . | ||
| 3 | 3 |
| Now, | 1 | work is done by A in 1 day. |
| 15 |
| 2 | work will be done by a in | 15 x | 2 | = 10 days. | |||
| 3 | 3 |
Hence, the total time taken = (10 + 2) = 12 days.
