In these type of questions,formula used isgain%=(Error/(true value-error))*100so 300/47=error/(True value-error)*1003/47=error/(1000-error)on solving u get error =60 if error is sixty that means he is using a weight of 1000-60=940gm

P(N) = 4000 √N.......taking n=16..P(N) = 4000 √16=16000..just assume. increasing n by 1%.....so n=16.16deb p(n)=4000*√16.16=16080....dividing 1680=.099=1so ans is 1

In the given question. n(e^t)=n(e)+n(t)-n(e or t)
n(e and t)=n - neither who speak English nor Telugu=150-30=>120.
n(e and t)=n(e)+n(t)-n(e or t)
120=55+85-n(e or t)
n(e or t)=20.
n(only Telugu)=n(t)-n(e or t)=85-20 = 65.
