1.	The C.I on ₹ 5000 at the rate of 8% for 2 years is ………………. A) ₹ 832 B) ₹ 238 C) ₹ 161 D) ₹ 169
Answer» Correct option is A) ₹ 832 Correct option is (A) ₹ 832 \(C.I.=P(1+\frac R{100})^n-P\) \(=5000(1+\frac8{100})^2-5000\) \((\because\) P = Rs 5000, R = 8% and n = 2 years) \(=5000(1+\frac{16}{100}+\frac{64}{10000}-1)\) \(=5000\times\frac{1600+64}{10000}\) \(=\frac{1664}2=832\) \(\therefore\) Required C.I. = Rs 832

The C.I on ₹ 5000 at the rate of 8% for 2 years is ………………. A) ₹ 832 B) ₹ 238 C) ₹ 161 D) ₹ 169

Answer»

Correct option is A) ₹ 832

Correct option is (A) ₹ 832

\(C.I.=P(1+\frac R{100})^n-P\)

\(=5000(1+\frac8{100})^2-5000\) \((\because\) P = Rs 5000, R = 8% and n = 2 years)

\(=5000(1+\frac{16}{100}+\frac{64}{10000}-1)\)

\(=5000\times\frac{1600+64}{10000}\)

\(=\frac{1664}2=832\)

\(\therefore\) Required C.I. = Rs 832
