ANSWER WITH SOLUTION

1.    (5)
Total executives recruited were 2953.

2.    (4)
Reqd. ratio = 1044:998
= 522:499

3.    (1)
Reqd. Average = 2965/6 ≈ 494

4.    (2)
Reqd. percentage increase = (54/418) × 100= 12.919≈12.92%

5.    (3)
Reqd. percentage = (510/2854) × 100 ≈18%

6.    (3)
Reqd. average = (650+300+150+450+300+400)/6 = 375 

7.    (4)
It is clear from the graph. 

8.    (2)
Reqd. average = 3900/6=650

9.    (5)
Reqd. percentage = (1100/1900) ×100≈58%

10.  (1)

Reqd. ratio = 1400:750=28:15
