simple interest on a certain sum of money for 2 years at 12 % per annum is half the compound interest on rs . 6000 for 2 years at 15 % per annum . the sum placed on simple interest is
"solution c . i . = rs [ 6000 x ( 1 + 15 / 100 ) â ² - 4000 ] rs . ( 4000 x 115 / 100 x 115 / 100 - 6000 ) = rs . 7935 . sum = rs . [ 3967.5 x 100 / 4 x 12 ] = rs . 8265.63 . answer c"
divide(multiply(divide(divide(add(divide(multiply(6000, 15), const_100), divide(multiply(add(6000, divide(multiply(6000, 15), const_100)), 15), const_100)), 2), 2), const_100), 12)
