DS Question1: Answer should be E.
1. There is no relation between Average of Set and Range of Set.
2. Range of subsets and Rage of bigger set could be different. Hence answer should be E.

DS Question2: Answer should be E.

1. K could be \(3x+2\)= 2,5,8,11,14,17,20,23,26
2. K could be \(5Y+1\)=1, 6,11,16,21,26

combine 1 & 2, K could be 11 or 26

PS Question3: \(LCM= 3*13*7*31=217*39= _,_,_,3\)so only option C has 3 in unit digit. Answer should be C.

PS Question4: Number of ways to select chairman=10, Number of ways to select an editor=9, Number of ways to select a secretary=8
so total number of selections= 10*9*8=720

Answer should be D.
