Question

At what rate percent per annum will rupees 800 amount to rupees 1000 5 years​

Answer 1

Answer:

Principal (p) = Rs 800

Amount (A) = Rs 1000

Time (t) = 2 years

Now,

Simple Interest (S.I) = A - p

= Rs (1000 - 800) = Rs 200

S.I = (p×r×t) /100

=> 200 = (800×r×2)/100

=> 200 × 100 = 1600 r

=> r = 20000/1600 = 12.50

Rate percent=12.5%
