Explanation:
Let the rate of interest be R% p.a.
(49500)(3)(R)/100 = 17820
495R = 5940
R = 12
CI on Rs.49500 at 12% p.a. for three years
= 49500{[1 + 12/100]3 – 1} = 69543.936 – 49500 = Rs.20043.94
when rounded off to two decimal places.

Answer: Option B
Explanation:
Let the middle digit be x.
Then, 2x = 10 or x = 5. So, the number is either 253 or 352.
Since the number increases on reversing the digits, so the hundred’s digits is smaller than the unit’s digit.
Hence, required number = 253.

By the rule of alligation:
|
Cost of 1 kg of 1st kind Cost of 1 kg of 2nd kind |
||
| 720 p | Mean Price 630 p |
570 p |
| 60 | 90 | |
Required ratio = 60 : 90 = 2 : 3.
