Question

a man gave rs.1200 on loan.some amount was given at a simple interest of 4% per annum and remaining at 5% per annum interest.if after 2 yrs he got rs.110as interest then found the amount given at 4% and 5% interests seperately.

Answer 1

simple interest means only 4% on the principle:? in that case put x = amount at 4% so 1200-x = amount at 5% and solve
\[.08x+.10(1200-x)=110\] for x

Answer 2

i get 500
