tell me the step
Ok
yes right the steps
n(u)=840,n(hindi)=450,n(English)=300,n(English and hindi)=200 then n(neither English and nor hindi)=n(hindi or English)'=n(u)-n(hindi or English)
n(hindi or English)=n(hindi)+ n(English)-n*hindi and English)=450+300-200
n(hindi or English)=550
don not -200 in this
So,n(hindi' and English')=n(u)-n(hindi or English)=840-550=290
