Correct Answer: 20

Solution : From the first condition,
$0.8A = 0.9B + 13$ ___(1)
From the second condition,
$\frac{0.4A}{0.6B} = \frac{10}{9} \Rightarrow 0.4A = \frac{10}{9} \times 0.6B$ ___(2)
From equation (2), we can express A in terms of B:
$A = \frac{10}{9} \times \frac{0.6B}{0.4} = \frac{5}{3}B$ ___(3)
Substitute equation

Correct Answer: 520

Solution : $\text{Average}$
$=\frac{\text{Sum of all observations}}{{\text{Total number of observations}}}$
$=\frac{500+505+515+530+550}{5}$
$=\frac{2600}{5}$
$= 520$
Hence, the correct answer is 520.

Correct Answer: 14 cm

Solution : In similar triangles, the ratio of their corresponding sides is equal to the ratio of their perimeters. 
Given that the perimeters of triangles RST and IJK are 56 cm and 64 cm respectively, the ratio of their perimeters is:
$\frac{\text{Perimeter of RST}}{\text{Perimeter of IJK}}

Correct Answer: INR 99

Solution : Given,
Cost price of X = Rs100
Final value = Initial value$(1 + \frac{R}{100}) (1 - \frac{R}{100}$)
Where, R = increment and decrement of Rate successively
Here, we have Initial value  = Cost price of X = INR 100, Rate of increment = 10%,
