Given : A man borrowed Rs.7800 at 6 1/2% simple interest from a bank. he lent Rs.3000 at 8% to John and remining money he lent Mohan at 7 1/2%
at the end 2 1/2 year both John and mohan returned the money .
To Find : How much gain did he get.
Solution:
SI = P * R * T /100
P = 7800
R = 6 1/2 = 13/2 %
T = 2 /12 = 5/2 Years
SI = 7800 * (13/2) * (5/2) /100 = Rs 1,267.5
To be paid to bank = Rs 1,267.5
P = 3000
R = 8 %
T = 2 /12 = 5/2 Years
SI = 3000 * 8 * (5/2) /100 = Rs 600
7800 - 3000 = 4800
P = 4800
R = 7 1/2 = 15/2 %
T = 2 /12 = 5/2 Years
SI = 4800 * (15/2) * (5/2) /100 = Rs 900
Total to be received = 600 + 900 = Rs 1500
Gain = 1500 - 1267.5
= Rs 232.5
He got gain of Rs 232.5
