Question

What sum lent out at CI will amount to Rs. $1936$ in $2$ years at $10$% p.a. interest?

• A. $1500$
• B. $1600$
• C. $1700$
• D. $1800$

Answer 1

Answer: (B)

$1600$

$\Rightarrow$ $A=P(1+\frac{R}{100}{)}^T$

$\Rightarrow$ $1936=P\times (1+\frac{10}{100}{)}^2$

$\Rightarrow$ $1936=P\times \left(\frac{121}{100}\right)$

$\Rightarrow$ $P=\frac{193600}{121}=Rs.1600$

$\therefore$ Sum lent out money is $Rs.1600.$
