Comments

Drama : 60

Dance : 80

Maths:30

Drama and dance and math = 2

Dance and drama = 30  ----> not sure about this

Dance and math = 12

Drama and math = 7

This question had a small caveat "only" , so 25% of students i.e 25% of X = 40 +30+ 60 + 15 + 7 + 12  - 2.

From there you can find X

is it correct or something missing in question ??

Answer 1

I got 900

Because in 2 clubs they didn't specifically said "only 2"

So I subtracted 2 from each

This why I got 900

Comments

no other option followed in the range of the calculations :P

975 and 225 25% isn't an integer:o

I too got 900 as answer. 225 was total Students that I got after solving Venn Diagram. and then 225*4=900
