in a certificate by mistake a candidate gave his height as 20 % more than actual height . in the interview panel , he clarified that his height was 5 feet 5 nches . find the % correction made by the candidate from his stated height to his actual height ?
"his height was = 5 feet 5 inch = 5 + 60 = 65 inch . required % correction = 65 * ( 1.20 - 1 ) = 13 a"
multiply(divide(subtract(add(20, add(const_0_25, const_0_25)), 5), add(const_100, subtract(add(20, add(const_0_25, const_0_25)), 5))), const_100)
