One day, the weather was bad and many students were absent. 3 classes were half full. 5 classes were 3/4 full and 2 classes were 1/6 empty. A total of 74 students were absent. What is the total number of students in this school?

best des
Hints: 3x/2 + 5×(x/4) + 2×(x/6) = 74
বা, 3x/2 + 5x/4 + x/3 = 74
বা, (18x + 15x + 4x)/12 = 74
বা, 37x = 888
x = 24
তাহলে, school এর student = 24×10 = 240
