Hello mate!
To find the required number of minutes
Let us find the LCM of 18 and 12
We have
18 => 2 × 3 × 3 = 2 × 3²
12.=> 2 × 2 × 3 = 2² × 3
LCM (18,12) => 2² × 3² = 36
After 36 minutes Sonia will be at the starting point after completing 2 rounds of the field and Ravi also be at same point after 3 rounds .
Hope it helps you
