difference of two numbers is 1660 . if 7.5 % of the number is 12.5 % of the other number , find the number ?
let the numbers be x and y . then , 7.5 % of x = 12.5 % of y x = 125 * y / 75 = 5 * y / 3 . now , x - y = 1660 5 * y / 3 – y = 1660 2 * y / 3 = 1660 y = [ ( 1660 * 3 ) / 2 ] = 2490 . one number = 2490 , second number = 5 * y / 3 = 4150 answer is a .
multiply(divide(7.5, 12.5), divide(1660, subtract(const_1, divide(7.5, 12.5))))
