Answer»

Number of days school attended/ Total Number days of school × 100= Percentage(%)

204/ x × 100 = 85204/85 × 100= x12/5 × 100= x12×20= x240= Total number of school.

Answer

Let the number of days the school was opened = Z

∴Percentage of attendance = 85% of Z

Now,

85% of Z = 204

⇒85/100×Z = 204

⇒Z = 204× 100/85

⇒Z = 204× 20/17 [Divided by 5]

⇒Z = 12× 20

⇒Z = 240

85x/100 = 20420400 = 85xX = 20400/85 =240no. of Days school opened= 240

240 is the best answer
