Question

Find a number such that the ratio of 5 ratio 2 to the number is the same as the ratio of the number to 5 ratio8​

Answer 1

Now if x=1, then m=4 So 4 must be added at least to make the new ratio 4:5. ... Let the number added be m,so that the ratio becomes 4:5. Now (8x+m)/( 11x+m)=4/5. On solving it ,we get=m=4x.
