mr. and mrs. singh have a child every J years. Their oldest child is now T years old. If they have a child 2 years from now, how many children will they have in total.

in this question, lets say j = 2 --> so they have kid every 2 years
oldest son = 12 years.

doesent that mean that they ALREADY have 6 children? and will have 1 more in 2 years so a total of 7?
