a) Rs. 1200
b) Rs. 1285
c) Rs. 1690
d) Rs. 1785
Answer: d
Explanation: Let the money added by Rahul be Rs. x
$$ \frac{{\left( {1150 + x} \right) \times 9 \times 3}}{{100}} – $$ $$\frac{{1150 \times 6 \times 3}}{{100}} = $$ $$274.95$$
1150 × 27 + 27x – 1150 × 18 = 27495
27x + 1150 × (27 – 18) = 27495
27x = 27495 – 10350
27x = 17145
x = 635
So, sum lent by Rahul to Sachin
= Rs. ( 1150 + 635 )
= Rs. 1785
