Question

One more than two scores is how much??

Answer 1

score= 20
so one more is 21

Answer 2

Given that normal of 70 understudies is 80.

This class is part into two gatherings of 40 and 30.

I am certain you will concur with me that if the normal of every one of these gatherings is 80, at that point the normal of the aggregate gathering i.e. 70 understudies will likewise be 80. In any case, the primary gathering of 40 understudies, rather than 80 they had a normal of just 75.

So certainly the normal of the rest of the 40 understudies must be more prominent than 80.
