ANSWERS WITH EXPLANATION

6.    2;   Required ratio = 4.5/2.4 = 15 : 8

7.    4;   Total number of employees

            = (5.7 + 4.8 + 3.4 + 4.5) × 1000

            = 18.4 × 1000 = 18400

8.    5;    K = 6.3, L = 4.7, M = 5.5, N = 5.3, P=5.6 , R = 2.9

             Required company = P

9.    3;   Required per cent = [7.2/(3.9+4.1+3.4+5.3+6.7+9.6)]*100

            = (7.2*100)/33 % =  21.82%  = 21% (Approx.)

10.  5;   Required average

            = [(6.3+4.7+5.5+5.3+5.6+2.9)/6]*1000

            = (30.3*1000)/6 = 30300/6 = 5050
