ratio of two numbers x and y is 3 : 7 . if x is increased by 50 % and y is increased by 2 then the new ratio becomes 1 : 2 . what is the ratio 2 y : ( 2 x + 6 )
"let : x = 3 n y = 7 n 4.5 n / ( 7 n + 5 ) = 1 / 2 9 n = 7 n + 2 n = 1 so , x = 3 ; y = 7 2 y / ( 2 x + 6 ) = 14 / 12 = 7 : 6 answer = c"
divide(multiply(2, multiply(divide(2, subtract(multiply(divide(add(const_100, 50), const_100), 2), divide(7, 3))), divide(7, 3))), add(divide(2, subtract(multiply(divide(add(const_100, 50), const_100), 2), divide(7, 3))), 2))
