Question

If the sum of the ages of A and B is 9 years more than the sum of the ages of B and C, then C is how many year younger than A

Answer 1

Let age of A = a
                 B = b 
                 C =c 

According to the question,



age of A + age of B = age of C + age of B + 9 years

a + b = c + b + 9 

a + b - b  = c + 9 

a = c + 9 

a -9 = c 


Then, we can say that C is 9 years younger than A
