Solution

Given: 
P = Rs 7, 500
R = 12 % p . a . = 3 % quarterly
T = 9 months = 3 quarters
We know that: 
\[A = P \left( 1 + \frac{R}{100} \right)^n \]
\[A = 7, 500 \left( 1 + \frac{3}{100} \right)^3 \]
\[ = 7, 500 \left( 1 . 03 \right)^3 \]
 = 8, 195 . 45
Thus, the required amount is Rs 8, 195 . 45.
