Question: Two numbers are respectively 25% and 40% more than a third number. The ratio of the two numbers is:

Solution:
Let,
the third number be 100.

∴ First number = 100 + 25% of 100
= 100 + 25
= 125

∴ Second number = 100 + 40% of 100
= 100 + 40
= 140

∴ Ratio of first to second = 125 : 140 = 25 : 28.
