Question

what principle will amount to rupees 15680 in 1 year 6 months at the rate of 8% p a simple interest?

Answer 1

Solutions :-

We have,
Amount (A) = Rs 15680
Time (t) = 1 year 6 months = 1.5 years
Rate (r) = 8% p.a = 0.08

To find :- principle = p


We know that,
A = p (1 + rt)
=> 15680 = p(1 + 0.08 × 1.5)
=> 15680 = p (1 + 0.12)
=> 15680 = p × 1.12
=> 15680/1.12 = p = 14000


Answer : Principle = Rs 14000

Answer 2

Solutions :-

Given :
Amount = A = Rs 15680
Time = t = 1 year 6 months = 1.5 years
Rate = r = 8% p.a

Let the principle be p


Find the principle (p) :-

We know,
A = p (1 + rt)
➠ 15680 = p ( 1 + 8% × 1.5)
➠ 15680 = p (1 + 0.08 × 1.5)
➠ 15680 = p (1 + 0.12)
➠ 15680 = p × 1.12
➠ 15680/1.12 = p = 14000


Hence,
Principle = Rs 14000
