Question

(1) Principal = 3200, r = 2.5 p.a, n = 2 years, interest compounded annually.
​

Answer 1

Step-by-step explanation:

Principal (P) = ₹ 3200

r = 2.5% p.a

n = 2 years comp, annually

∴ Amount (A) = (1 + r/100)

n = (1 + 2.5/100)2 = 3200 x (1.025)2 = 3362 Compound interest (Cl) = Amount – Principal

= 3362 – 3200 = ₹ 162
