Answer is : Rs.5,000
Let he borrowed Rs x
borrows money at 4% per annum and pays the interest at the end of the year
Amount he has to return = 104x100
Amount he will get = (1+3100)2=1060910000x
His gain = 1060910000x=104100x=104.50
x(1060910000−104100)=104.50
x(1060910000−1040010000)=104.50
x(10609−1040010000)=104.50
x(20910000)=104.50
x=104.50∗10000209
x=Rs 5000
