2a) A sum of money lent out at simple interest at the rate of 9% for 5 years produces twice as much
interest as 74800 in 4 years at 10%. Find the sum.​

Answer 1

Answer:

The sum is Rs. 1,32,977.778

Step-by-step explanation:

Let P be the sum

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

Case I

$I = \frac{p \times 9 \times 5}{100}$

Case II

$2 \times ( \frac{74800\times 4 \times 10}{100} ) = I$

$2 \times (748 \times 10 \times 4) = \frac{P \times 9 \times 5}{100} \\ P = \frac{2 \times 748 \times 4 \times 10 \times 100}{9 \times 5} \\ P = 132977.778$
