(b) ₹ 5051
Explanation:
Present value= ₹ 25000
Interest rate for first year, p= 5 % per annum
Interest rate for second year, q= 6 % per annum
Interest rate for second year, r= 8 % per annum
Amount (A) = P × (1+p/100) × (1+q/100) × (1+r/100)
Now substituting the values in above formula we get,
∴ A = 25000 × (1+5/100) × (1+6/100) × (1+8/100)
⇒ A = 25000 × (105/100) × (106/100) × (108/100)
⇒ A = 21 × 53 × 27
⇒ A = ₹ 30051
∴ Compound interest = A – P
= 30051 – 25000= ₹ 5051
