compound interest MCQs Math for Preparation of PPSC, FPSC, and NTS exams
What will be the compound interest on a sum of Rs. 25,000 after 3 years at 12% p.a.?
A. Rs. 9000.30
B. Rs. 9720
C. Rs. 10123.20
D. Rs. 10483.20
Amount = [25000 * (1 + 12/100)3]
= 25000 * 28/25 * 28/25 * 28/25 = Rs. 35123.20
C.I. = (35123.20 – 25000) = Rs. 10123.20
A man saves Rs. 200 at the end of each year and lends the money at 5% compound interest. How much will it become at the end of 3 years?
A. Rs. 565.25
B. Rs. 635
C. Rs. 662.02
D. Rs. 666.50
Amount = [200(1 + 5/100)3 + 200(1 + 5/100)2 + 200(1 + 5/100)]
= [200 * 21/20(21/20 * 21/20 + 21/20 + 1)] = Rs. 662.02
Hafeez invested Rs. 15000 at 10% per annum for one year. If the interest is compounded half-yearly, then the amount received by Hafeez at the end of the year will be?
A. Rs. 16,500
B. Rs. 16,525.50
C. Rs. 16,537.50
D. Rs. 18,150
P = Rs. 15000; R = 10% p.a. = 5% per half-year; T = 1 year = 2 half-year
Amount = [15000 * (1 + 5/100)2] = (15000 * 21/20 * 21/20) = Rs. 16537.50
