Answer 2

Question-

15. Gaurav went to school for 216 days in a full year. If his attendance is 90% find the number of days on which the school was opened. ​

Answer-

Le the total required number of days be x.

Then,

90% of x = 216

⇒ 90/100 × x = 216

⇒ 9/10 × x = 216

⇒ x = 216 × 10/9

⇒ x = 24 × 10

⇒ x = 240

The number of days on which the school was opened is 240 days.
