What equal installment will discharge a debt of Rs. 1007 due in 5 years, rate of interest being 3% p.a.?
Explanation:
A = 1007, t = 5 years, r = 3%
∴ A = x1+R×(T-1)100 + x1+R×(T-2)100 + ... + x
⇒ 1007 = x1+3×4100 + x1+3×3100 + x1+3×2100 + x1+3×1100 + x
⇒ 1007= x5+3×10100
⇒ x = 1007053 = 190
Hence, option (b).
