    The sum of age of the two new boys = 56 years

    Step-by-step explanation:

    The average age of a group of 13 boys = 13

    The sum of age of the 13 boys = 13 * 13 = 169

    The average age of a group of 15 boys = 15

    The sum of age of the 15 boys = 15 * 15 = 225

    The sum of age of the two new boys = 225 - 169 = 56 years
