A man borrows a sum of Rs 50000 for two years at 20% p.a compound interest, interest being compounded annually. If he repays Rs 24000 at the end of the second year and clears the debt how much did he pay at the end of the first year
30000
32000
40000
37500
one of the correct values are
1.2x^2
2.2 rt (x^2-y^2)
3.2 rt(x^2+y^2)
4.2x
