the answer is option d=>60

Answer 2

Solution :

During a parent teacher meeting , 75 people attended . Among them, 80% were parents . We have to find out how many parents were present. Let us assume that there were x parents present. Then 80% of 75 = x

So

x = 80% of 75

> (80/100) x 75

> (4/5) x 75

> 4 x 15

> 60

Hence, a total of 60 parents were present in the meeting. The correct answer is (D) .
