What is the average of positive integers from 1 to 100 inclusive?
(A) 49
(B) 49.5
(C) 50
(D) 50.5
(E) 51

Answer 1

Aslam has 4 times as many books as Salman and 5 times as many as Javed.
If Javed has more than 40 books, what is the least number of books that
Aslam could have?
(A) 200 (B) 205 (C) 210 (D) 220 (E) 24

Answer 2

average = (1+100) / 2

Answer 3

Javed has more than 40 books , so least he can have is 41
so aslam would then have 41* 5 = 205 books
but aslam has 4 times as many books as Salman so 205 cannot be the correct amount
So what do you think we should try next?

Answer 4

the number of books that aslam has must be divisible by 4 and 5
