Question

At which sum will the simple interest at the rate of $3\frac{3}{4}\%$ per annum be Rs. $210$ in $2\frac{1}{3}$ years?

• A. Rs. $1580$
• B. Rs. $2400$
• C. Rs. $2800$
• D. None of these

Answer 1

Answer: (B)

Rs. $2400$

We know that:

$SI=\frac{PRT}{100}$

Substituting the values:

$⟹210=\frac{P\times \frac{15}{4}\times \frac{7}{3}}{100}$

$⟹P=\frac{210\times 100\times 12}{15\times 7}=Rs.2400$
