Correct Answer: Rs. 788.48

Solution : The formula for the difference between Compound Interest(CI) and Simple Interest(SI) for 3 years is given by:
$CI-SI=\frac{PR^{2}(300+R)}{100^{3}}$, where $P$ is principal and $R$ is rate of interest per annum compounded annually.
⇒ $CI-SI=\frac{40000\times8^{2}\times(300+8)}{100^{3}}$
⇒ $CI-SI=\frac{788480000}{1000000}$
$\therefore CI-SI=788.48$
Hence, the correct answer is Rs.

Correct Answer: 1199

Solution : Given:
17 : 4607 :: 11 : ? :: 23 : 11615

The pattern is as follows –
4607 ÷ 17 = 271; The sum of the digits is 2 + 7 + 1 = 10
11615 ÷ 23 = 505; The sum of the

Correct Answer: Rs. 9,200

Solution : Given: The difference between the cost price and selling price = Rs. 1200
The difference in percentage between the cost price and selling price = 15%
$\because$ Both the differences are equal.
Thus, $\frac{15}{100}$ of the cost price = 1200
$\therefore$ The cost price

Correct Answer: 3

Solution : Given:
?, 11, 35, 107, 323

Here, the pattern is as follows –
(11 × 3) + 2 = 33 + 2 = 35;

Correct Answer: 6

Solution : Given number = $846523X7Y$
Sum of digits = $35+X+Y$
Maximum value of $35+ X+Y = 35+18=53$
Minimum value of $35+X+Y = 35$
For a number to be divisible by 9, the sum of digits of the number should be divisible by 9.
So, the sum
