ANSWERS WITH EXPLANATION

1.    2;   Required % = [(1296-1280)/1296]*100

            = 1.234 (decrease)

2.    4;   Required % = (575/925)*100

            = 62% (approx)

3.    3;   Required difference = 701.25 – 268.25 = Rs. 433

4.    1;   Required% = (1472/1456)*100

            = 101% (approx)

5.    4;   Required amount = 94 + 160.75 + 8.15 + 406 = Rs. 668.9

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
