ratio of two numbers x and y is 7 : 9 . if x is increased by 20 % and y is increased by 33 then the new ratio becomes 1 : 5 . what is the ratio 2 y : ( x + 4 )
let : x = 7 n y = 9 n 8.4 n / ( 9 n + 33 ) = 1 / 5 42 n = 9 n + 33 n = 1 so , x = 7 ; y = 9 2 y / ( x + 4 ) = 18 / 11 answer = a
divide(multiply(const_2, multiply(divide(33, subtract(multiply(divide(add(const_100, 20), const_100), 5), divide(9, 7))), divide(9, 7))), add(divide(33, subtract(multiply(divide(add(const_100, 20), const_100), 5), divide(9, 7))), 4))
