Answer 2

Given :-

• Ben goes to the park once in every 5 days .
• Bob goes once in 9 days .

To Find :-

• If they met each other on day 1, when will they meet again ?

Solution :-

We know that, next time they will meet again will be the LCM of their individual days .

so, Prime factors of 5 and 9 :-

→ 5 = 1 * 5

→ 9 = 3 * 3

LCM = 5 * 3 * 3 = 45 days.

Hence, they will meet again after 45 days.
