• A. Rs. 120
• B. Rs. 104
• C. Rs. 116
• D. Rs. 122

Answer 1

Answer: (D)

Rs. 122

$P=85$, $T=3years$ , $SI=95-95=10$

In first case, we have

$\frac{P\times R\times T}{100}=SI$

$\Rightarrow$ $\frac{85\times R\times 3}{100}=10$

$\Rightarrow$ $R=\frac{200}{51}$ %

In later case, $P=102$, $T=5$, $R=\frac{200}{51}$

$\Rightarrow$ $SI$ $=\frac{102\times 200\times 5}{100\times 51}=20$

$\Rightarrow$ $A=P+SI=102+20=122$
