38 years old.

Explanation:

So, we are given the following data or parameters or information which is going to assist us in solving this particular Question;

1=> The three children are A, B and C respectively.

2=> "the present age of husband is 5 years more than the wife's age."

3=> " the wife's age is twice the present age of A"

4=> the present age of A is 12 years more than the present age of B "

5=> B's present age is one and a half times the present age of C .

6=> "if C is 12 years old at present "

7=> "husband's friend Ram who is 15 years younger than the husband"

We will start from point 5 above that is to say;

B = C × 3/2. = 12 × 3/2 = 6 × 3= 18.

Also, A = 12 + B = 12 + 12= 24.

From the point 3 Above; the wife's age= 2 × A= 2 × 24 = 48 years of age.

From the point 2, we have that the husband's age = 5 + 48 = 53 years of age.

Thus, the present age of husband's friend, Ram who is 15 years younger than the husband = 53 - 15 = 38 years old
