Question

Rakesh lent out Rs 8000 for 5 years at 15% per annum. How much did he gain or lose?

Answer 1

Given,
P=Rs8000
T=5yr
R=15%
SI=P*R*T/100
=8000*15*5/100
=Rs6000
therefore ,A =P+SI
=8000+6000
=Rs14000
therefore,
Rakesh gained =1400-8000
=Rs6000

Answer 2

Answer:

income- 8000×5×15/100=6000

expenditure- 6000×3×12/100=2160

Gain= income-expenditure

6000-2160= Rs. 3840.

hope its help you....
