Q:

A) Rs. 2000 | B) Rs. 2100 |

C) Rs. 1900 | D) Rs. 2150 |

Answer & Explanation
Answer: A) Rs. 2000

Explanation:

Explanation:

Given,

Compound rate, R = 10% per annum

Time = 2 years

C.I = Rs. 420

Let P be the required principal.

A = (P+C.I)

Amount, A = {}

(P+C.I) = {}

(P+420) = P[11/10][11/10]

P-1.21P = -420

0.21P = 420

Hence, P = 420/0.21 = Rs. 2000
