Question

Rahul borrowed Rs. 830 from Mr. Lal at 12% p.a. S.I. for 3 years. He then added some more money to the borrowed sum and lent it to Shobha for the same period at 14% p.a. rate of interest. If Rahul gains Rs. 93.90 in the whole transaction, how much money did he add from his side?

• A. Rs. 35
• B. Rs. 55
• C. Rs. 80
• D. Rs. 105

Answer 1

The correct option is D Rs. 105

$\frac{(830+x)\times 14\times 3}{100}-\frac{830\times 12\times 3}{100}=93.90$

$or830\times 42+42x-830\times 36=9390$

$42x=9390-4980$

$\Rightarrow x=\frac{4410}{42}=105$

$\therefore Moneyadded=Rs.105$
