ratio x:y?
​

Answer 1

Answer:

Here given sum of 50%of x that is 50x/100and 40%of y that is 40y/100 equal to 75%of y that is 75y/100 and 20% of x that is 20x/100

A/q

50x/100 + 40y/100 = 75y/100 +20x/100

50x/100 - 20x/100 = 75y/100 - 40y/100

3x/10 = 35y/100

300x = 350y

x/y = 300/350

x/y = 6/7

x:y =6:7

Hope this will be help u
