Question

The sum of age of 3persons is 20 years before 2 years what is the sum of their age after 2years

Answer 1

Answer:

32

Step-by-step explanation:

Let the ages of the 3 persons before 2 years be a, b, c respectively

Before 2 yrs, a+b+c=20

Present sum of ages=(a+2)+(b+2)+(c+2)=a+b+c+6=20+6=26

After 2 years, sum of ages=(a+2+2)+(b+2+2)+(c+2+2)= a+b+c+12=20+12=32
