Twinkle tellsRaveena that she has got 3 kids and 2 of these kids are twins, andalso that their ages are all integers. She tells Raveena the sum of theages of her kids and also the product of their ages. Raveena says thatshe has insuficient information to determine the ages, but onepossibility is that the twins are a prime number of years old. IfTwinkle's twins are teenagers and their age is not prime, then the sumof the ages of her kids is
