difference of two numbers is 1860 . 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 = 1860 5 * y / 3 – y = 1860 2 * y / 3 = 1860 y = [ ( 1860 * 3 ) / 2 ] = 2790 . one number = 2790 , second number = 5 * y / 3 = 4650 . answer d ."
multiply(divide(7.5, 12.5), divide(1860, subtract(const_1, divide(7.5, 12.5))))
