Question

Simple interest on a sum at 3 per annum in 4 years is Rs. 70. Find the sum.​

Answer 1

☆ANSWER:

Given:

• Simple interest = ₹70
• Rate = 3%
• Time = 4 yrs

A.T.Q:

We know, Principal = $\frac{SI\times 100}{R\times T}$

So, the sum = $\frac{70 \times 100}{4 \times 3}$

₹583.33 is the sum.

Extras:

• P = $\frac{SI\times 100}{R\times T}$

• R = $\frac{SI\times 100}{P \times T}$

• T =$\frac{SI\times 100}{P \times R}$

Answer 2

Answer:

The sum is found to be 583.34

Step-by-step explanation:

We have been mentioned here that the simple interest on a total sum at the rate of 3 percent per annum in 4 years is given Rs 70. Let us assume the total principal sum to be Rs m. Therefore we have;

S.I = $\frac{PRT}{100}$

⇒ S.I = $\frac{m (3) (4)}{100}$

⇒ 70 = $\frac{3m}{25}$

⇒ 70 × 25 = 3m

⇒ 3m = 1750

⇒ m = $\frac{1750}{3}$

⇒ m = Rs 583.34

Therefore the sum is Rs 583.34
