The product of the ages is 36. So, following combination of ages are possible:

1, 1, 36 | sum = 38
1, 2, 18 | sum = 22
1, 3, 12 | sum = 16
1, 4, 9 | sum = 14
1, 6, 6 | sum = 13
2, 2, 9 | sum = 13
2, 3, 6 | sum = 11
3, 3, 4 | sum = 10

When man had said that the product of the ages is equal to 36, the officer didn't have enough information. When the man said that the sum of their ages equals to number of shops in front of the office the officer could not again still understand because there must be more than one such combination possible. In fact from the above, we can see it can only be 13. So the sum of the ages should be 13, because otherwise he would have known the ages immediately. The last statement is that that the oldest child loves chocolate. So there is an oldest child. Hence the officer concludes that the ages of the children are 2, 2 and 9 years.

answer is 1,4,9

the product is equal to 36 which is satisfied by every option

the sum of the ages is equal to the shops infront of the office

the sum of different options are 14,13,16,11

person can become confuse between 13 n 14 but not between 11 n 14 or 16 n 11

so the last two options are ruled out

as the man says my oldest duaghter the option 2 is also ruled out because if it 2,2,9 then he only have to say my older daughter so the answer is 1,4,9
