A sum invested at 5% simple interest grows to Rs.504 in 4 years. The same amount at 10% simple interest in \( \Large 2\frac{1}{2} \) years will grow to

A) Rs.420
B) Rs.525
C) Rs.450
D) Rs.550

Correct Answer:


B) Rs.525

Description for Correct answer:
If x is amount, then

\( \Large x + \frac{5 \times 4 \times x}{100} = 504 \)

Amount after \( \Large 2\frac{1}{2} \) years at simple interest of 10%

= \( \Large 420 + \frac{420 \times 5 \times 10}{2 \times 100} \) = Rs.525.00
