Answer 1

PLEASE MARK AS BRAINLIST!!!!

Amount invested = Rs 2, 15, 000.   Amount obtained = Rs 3, 05, 000.=> Amount gained = total interest for 2 years = Rs 90, 000.=>  Gain per Rs 1, 000 of investment             = 90,000/2,15,000 * 100 = 41.86%
Mr. Ramniklal:   investment :  Rs 1, 40, 000   Rate of interest = 8%  C.I.   period = 2  years   Maturity amount = A = Rs 1,40,000 * (1 + 8/100)²      = 1,40,000 * 1.08²      = Rs 1, 63, 296  Amount (interest) gained in 2 years = Rs 23, 296.=> amount gained per 1000 of investment        = 23, 296/1,40,000 * 100 = 16.64 %
So Mr. Hiralal's investment was better and more profitable.
