Answer 1

Step-by-step explanation:

882=1*2*3*3*7*7

The ages of four children are of different ages and under 18

We need to consider p,q,r,s such that they are different, they are under 18 and

P*q*r*s=882

While one '7' has to be taken as one child's age, the other '7'has to be multiplied by 2.( As 7*3. Is ruled out)

Hence we can take p=14, q=7.

The factors we are left with are 1,3,3. The ages that can be considered so that the product p*q*r*s=882 are r=3*3,s=1

882=14*7*9*1

The sum of their ages=14+7+9+1=31
