Question 17
Rajni and Mohini deposited Rs. 3000 and Rs. 4000 in a company at the rate of 10 % per annum for 3 yr and 212yr, respectively. The difference of the amounts received by them will be
(a) Rs. 100
(b) Rs. 1000
(c) Rs. 900
(d) Rs. 1100
For Rajni, P = Rs. 3000,
R = 10 % per annum
T = 3 yr
∴ I=P×R×T100=3000×10×3100=Rs900and A=P+I=3000+900=Rs.3900For Mohini, P=Rs.4000,R=10% per annumand T=212yr=52yr∴I=P×R×T100=4000×10×5100×2=Rs.1000and A=P+I=4000+1000=Rs.5000
Difference in amounts = 5000 - 3900 = Rs. 1100
