Col B: (-1)^n
ans : C
1)if the integers are 10,20,30....250 in dat case m is 5 or 10 .
ReplyDeleteif integers are 10,15,30...m is 5
so m can be 5 or 10...hence c

1)here are 25 positive integers and each integer is a multiple of m. Highest of these integers is 250.
ReplyDeleteCol A: m
Col B: 5
For this they have simply mentioned that 25 numbers and all are multipe of m. Since highest number 250 will also be a multiple of m... value of m can be any of the divisors of 250... i.e m can be either of 2, 5 or 10. Hence answer to this is D
