Question

ind the sum which will amount to 700 in 5 years at 8% p.a​

Answer 1

Amount = ₹ 700, Rate (R) = 8% p.a.

Time (T) = 5 years

Let principal (P) = ₹100

Then S.I. = (P × R × T)/100 = (100 × 8 × 5)/ 100 = ₹ 40

∴ Amount (A) = P + S.I.

= ₹100 + 40 = ₹140

If amount is ₹140, then principal = ₹ 100

And, if amount is Rs. 700, then Principal

= ₹ (100 × 700)/140 = ₹ 500
