Question

If 15 of x y )= 25 of xy then what percent of y is equal to x

Answer 1

Answer:

15% of x = 25 % of y

3x/20 = y/4

x/y = 5/3

x is what % of y

= 5*100/3 = 500/3 % (Ans)

Answer 2

Answer:

50% of (x -y) = 30 of (x +y)

50 (x -y) = 30 (x +y)

50x - 50y = 30x + 30y

20x = 80y

y/x = 20/80

% of x is y = (20*100)/80 = 25%.
