Answer 2

Hey there!
Down here ⏬

Given Datas

Product of thier ages = 72

✓ Find the LCM of 72 (Refer Attachment)

$72 = 2 \times 2 \times 2 \times 3 \times 3$

✓ The elder child had started to take piano lessons.

So, His age =
$2 \times 2 \times 2 = 8$
$rest \: two \: children = 3 \: and \: 3$
$age \: of \: \: children \: = \: 3 \: 3 \: and \: 8$

So, John's Bith Date =
$3 + 3 + 8 = 14$

Hence, the ages of the three children are 3,3, and 8

Hope helped.
