Question

On what sum of money does the S. I. For 10 years at 5% become ₹1, 600?

Answer 1

Answer:

Let the sum of money be Rs. x.

According to the question,

Principal Amount = Rs. x

Rate = 5%

Time Period = 10 years

SI = Rs. 1600

We know that,

$\boxed{ \bf{ SI = \dfrac{PRT}{100}}}$

Hence substituting the known values we get:

$\implies 1600 = \dfrac{ x \times 5 \times 10}{100}\\\\\\\implies x = \dfrac{1600 \times 100}{5 \times 10}\\\\\\\implies x = \dfrac{160000}{50}\\\\\\\implies \boxed{ \bf{ x = Rs.\:3200 /-}}$

Hence the required answer is Rs. 3,200.

Answer 2

Given :

• On what sum of money does the S. I. For 10 years at 5% become ₹1, 600

Solution :

S.I. = Rs. 1600, R = 5% p.a.

T = 10 years

∴ P = (S.I. × 100)/(R × T) = 1600 × 100/5 × 10 = Rs . 3200
