Question

A sum, when invested at 12.5% simple interest per annum, amounts to 8,250 after 2 years. What is the simple interest?

• A. ₹1,820
• B. ₹1,650
• C. ₹1,910
• D. ₹1,700

Answer 1

Answer:

B. ₹1,650

$P+SI=8250$

$SI=\frac{P\times 12.5\times 2}{100}$

$SI=\frac{25P}{100}=\frac{P}{4}$

$P-\frac P4=8250$

$\frac{3P}{4}=8250$

$P=\frac{4\times 8250}{3}=1650$
