প্রশ্ন: Two-thirds of the teachers of high school are women, twelve of the male teachers are unmarried while 3/5 of the male teachers are there in the school?
ব্যাখ্যা:
Let, total members are x then female members are 2x/3 So,
male members are = x 2x/3 = x/3
ATQ, 12 teachers are unmarried Or, (100 - 60)% = 40% = 12 So, 100% = 12*100/40 = 30
Again, x/3 = 30 Or, x = 90
Now, total faculty members are 90
Answer:90
