Question

The sum of the present age of a, b and c is 180 years. 12 years ago their ages were in the ratio of 1:2:3. What is the present age of c?

Answer 1

Answer:

Present age a+b+c =180

12years ago a-12+b-12+c-12=180; 180-36=144

1:2:3=144; 3/6 *144=72

72 is c`s age 12 years ago

Present age of C=72+12=84
