Question

If (x +y ) is more than ( x−y ) by 40% of (x – y), then how much percent of y is x

Answer 1

Answer:

(x-y) * 40/100

(x-y) * 2/5 + (x-y) = (x+y)

2/5 (x-y) = 2y

2x-2y = 10y

2x = 12y

x = 6y

Answer 2

Step-by-step explanation:

$x + y = 140 \div 100(x - y) \\ 100(x + y) = 140(x - y) \\ 5x + 5y = 7x - 7y \\ 7x - 5x = 5y + 7y \\ 2x = 12y \\ x = 6y \\ so \: y \: is \: \\ 1 \div 6 \times 100 = 16.66\%$

y is 16.66℅ of x
