- In a class 80% have passed english,( 20% failed), 70% passed Hindi (30% failed in Hindi) and 10% did not passed either.
If there are 100 students,
Total failed in any subject = 20+30-10= 40
Total pssed in both subjects = 60
so If 144 students passed both, the total strength of the class 144*100/60= 240 students - 11 years agoHelpfull: Yes(12) No(5)
