The age of A is 4 times the age of B and C is 9 years younger than B. Find the age of C if the sum of their ages is 63.

Ans:
Let B's age be x
A's age = 4*x
C's age = x - 9
Sum = 4%2Ax+%2B+x+%2B+x+-+9+=+63
i.e. 6%2Ax+=+72 or x+=+12

So B's age = highlight%2812%29
A's age = 4%2A12 = highlight%2848%29
C's age = 12+-+9 = highlight%283%29

Hope you got it :)
