Question

Some amount out of Rs 7000 was lent at 6% p.a. and the remaining at 4% p.a. If the total simple interest from both the fractions in 5 years was Rs 1600, the sum lent at 6% p.a. was:

• A. Rs 3000
• B. Rs 4000
• C. Rs 5000
• D. Rs 2000
• E. None of the above

Answer 1

The correct option is D Rs 2000

Overall rate of interest =$\frac{1600\times 100}{5\times 7000}=\frac{32}{7}\%$

$\therefore$ Ratio of two amounts = 2 : 5
$\therefore$ Amount lent at 6% =$\frac{2}{7}\times 7000=Rs2000$
