a sum of 14,400 amounts to 16,600 in 3 years at the rate of simple interest . what is the rate of interest ?
"d 5 % s . i . = ( 16600 - 14400 ) = 2200 . rate = ( 100 x 2200 ) / ( 14400 x 3 ) % = 5 %"
multiply(divide(divide(const_3, 3), add(multiply(const_3, 3), add(const_0_25, const_0_25))), const_100)
