Question

A certain amount becomes?8325 in 4 yrs at the rate of 5.5%p.a. Find the interest​

Answer 1

Step-by-step explanation:

We Know That Some Formula

S.I = P × R × T / 100

P = Principle

R = Rate

T = Time

Given in Questions

Amount = Rs 8325

Time = 4 year

Rate = 5.5 %

Let the Principle amount be P

We Know That , S.I = P × R × T / 100

Amount ( A ) = P + S. I

Therefore A = P + P × R × T / 100

8325 = P + P × 5.5 × 4 / 100

8325 = P + P × 55 × 4 /1000 ( remove point One place to 5.5 and increase 0 is Denominator )

8325 = P + P × 11 × 4 / 50

8325 = P/1 + 11 P / 50

8325 = 50 P + 11 P / 50

61 P = 8325 × 50 ( Transposing Digit to each other side )

P = 8325 × 50 /61 ( Divided 61 to 8325 )

P = 136.47×50

P = 6823.50

Therefore Interest = Amount - Principle

= 8325 - 6823.5

= Rs 1501.5

The Interest is Rs 1501.5
