Solution

1.Average profit earned by three companies in 2008
= (400 + 450 + 350)/3
= Rs.400 crore

2.Required difference in 2007 = Rs.25 crore

3.Total profit earned by three companies:
In 2009 = (400 + 425 + 475) = Rs.1300 crore
In 2008 = (450 + 400 + 350) = Rs.1200 crore

4.Required %increase = [(375 - 275)/275] × 100 = 36% (approx)

5.Required difference = (400 - 300) = Rs.100 crore

6.Marks obtained by
Rajeev = 192
Narendra = 192
Amit = 252
Veena = 201
Ramesh = 208

7.Required difference
= (201/3) - (192/3)
= 9/3
= 3

8.Required% = (208/300) × 100 = 69% (approx)

9.Required% = [(90 - 74)/90] × 100 = 18% (approx)

10.Required ratio = 372 : 356 = 93 : 89
