The ratio of the number of men to the number of women on a bus was 2 : 3. at a bus stop, 4 women got off and the ratio became 4 : 5. a) how many men were on the bus? b) how many women were on the bus in the end?

We have m / w = 2 / 3;

Then, m / ( w - 4 ) = 4 / 5;

m = 2w / 3 and 5m = 4w - 16;

5 x ( 2w / 3 ) = 4w - 16;

10w / 3 = 4w - 16;

10w = 12w - 48;

2w = 48;

w = 24 (woman were on the bus in the beginning);

A) m = ( 2 x 24 ) / 3 = 16 (men were on the bus );

B) 24 + 4 = 28 woman were on the bus in the end;
