In how many years, Rs. 200 will produce the same interest @ 5 % as Rs. 900 produce in 2 years @ 3 ½ %?
Choose one.
A) 6.3 years B) 8.2 years C) 9 years D) 12 years E) None of these
Explanation:   P = Rs 900, R = 3 ½ % = 7/2 %, T = 2 years.   Therefore,   S.I. = PRT/100   S.I. = Rs. (900 x 7/2 x 2/100) = Rs. 63   Now, P = Rs. 200, S.I. = Rs. 63, R = 5 %   Time = ((100 x 63) / (200 x 5) ) years = 6.3 years   6.3 yearsNSWER 6.3 years
