# If the Ratio Between 8 and 11 is the Same as the Ratio of 2x - Y to X + 2y. Find the Value of (7x)/(9y) - ICSE Class 10 - Mathematics

#### Question

If the ratio between 8 and 11 is the same as the ratio of 2x - y to x + 2y. Find the value of (7x)/(9y)

#### Solution

(2x - y)/(x + 2y) = 8/11

22x - 11y = 8x + 16y

Given 14x =27y

x/y = 27/17

(7x)/(9y) = (7 xx 27)/(9 xx 114) = 3/2

Is there an error in this question or solution?
