(A) 240
 (B) 220
(C) 280
(D) 210
Answer : D
Explanation :
a1= 0*1*2 =0
a2 =1*2*3 = 6
a3= 2*3*4= 24

a5=4*5*6=120
a6=5*6*7=210

8. A group of 7 members having a majority of boys is to be formed out of 6 boys and 4 girls. The number of ways the group can be formed is
(A) 80
 (B) 100
(C) 90
 (D) 110
Answer : B
Explanation :
4 -------3 --- (6C4)(4C3) = (15)(4) = 60 
                 (6*5*4*3/4*3*2*1)*(4*3*2/3*2*1)

5 -------2 ----(6C5)(4C2) = (6)(6) = 36 
                (6*5*3*4*3/5*4*3*2*1)*(4*3/2*1)

6 -------1 ----(6C6)(4C1) = (1)(4) = 4 
                 (6*5*4*3*2*1/6*5*4*3*2*1) * (4/1)

So 60+36+4=100

9. The number of observations in a group is 40. The average of the first 10 members is 4.5 and the average of the remaining 30 members is 3.5. The
average of the whole group is
(A) 4
(B) 15/2
(C) 15/4
(D) 6
Answer : C
Explanation :
Given :
Total observations = 40
Average of First 10 observations = 4.5
Average of Remaining 30 observations = 3.5

Average of Total observations = (Sum of 10 members + Sum of Remaining 30 members ) / Total observations
Sum of First 10 members = 4.5 x 10 = 45
Sum of Remaining 30 members = 3.5 x 30 = 105

Hence, Average of Total observations = (45 + 105) / 40
= 150 / 40
Average of Total observations = 3. 75
