Question

in what period the sum of rs 10,000 will earn a simple interest of 3200@8% per annum​

Answer 1

S O L U T I O N :

Given :

• Principal, (P) = Rs.10000
• Simple Interest, (SI) = Rs.3200
• Rate, (R) = 8% p.a

Explanation :

As we know that formula of the Simple Interest :

• S.I = Principal × Rate × Time/100

According to the question :

➝ Simple Interest = PRT/100

➝ Time = S.I × 100/P × R

➝ Time = 3200 × 100/10000 × 8

➝ Time = 320000/80000

➝ Time = 32/8

➝ Time = 4 years

Thus,

The time or period of the interest will be 4 years .

Answer 2

Answer:

Given :-

• A sum of Rs 10000 will earn a simple interest of Rs 3200 at the rate of 8% per annum.

To Find :-

• What is the time period.

Formula Used :-

✦ Time = S.I × 100/Pr ✦

where,

• S.I = Simple Interest
• P = Principal
• r = Rate of Interest

Solution :-

Given :

• Principal = Rs 10000
• Rate of Interest = 8 %
• Simple Interest = Rs 3200

According to the question by using the formula we get,

⇒ Time = 3200 × 100/10000 × 8

⇒ Time = 320000/80000

➠ Time = 4 years

∴ The time period is 4 years .
