There are two numbers 'x' and 'y'. 40% of 'x' is equal to 60% of 'y'. If the average of 'x' and 'y' is 225, then what is the difference between 'x' and 'y'?
Answer & explanation
Correct answer: option 4
Total sum of x & y = 2 × 225 = 450
Given :- 40% of 'x' is equal to 60% of 'y'
So , Ratio of x to y is 3 : 2
According to question ,
5R = 450
1R = 90 ( difference 3R - 2R = 1R )
So , Difference is 90
