Question: The ratio of present age of rahul and after 15 years is 3:4 find the present age


Solution:

tips - For problems like this we need to consider x for unknown and proceed.

Ratio is the proportion that is 3:4 means 3/4.

LET the present  age of rahul be x

Therefore his age after 15 years is x + 15

So the equation is 

x/x + 15  = 3/4

expanding the equation

4x = 3x + 45

x= 45 

That is the present age of rahul is 45.
