### Answers & Solutions :

**1.c**

**40/100 = (I – 400)/400**

**==> Income = 560**

**2.a**

**35/100 = (300 – E)/E**

E = 222.22 crore

E = 222.22 crore

**3.c**

**35/100 = (I – E1)/E1**

**==> I = 27E1/20 ---(i)**

**30/100 = (I – E2)/E2**

**==> I = 13E2/10**

**E1/E2 = 26 : 27**

**4.c**

**% profit in 2010 = 30%**

% profit in 2012 = 40%

% increase = (10/30)*100 = 33.33%

% profit in 2012 = 40%

% increase = (10/30)*100 = 33.33%

**5.b**

**Company 1 = 60/100 = (I – E)/E**

**==>I1 = (8/5)*E**

Company 2 = 50/100 = (I -E)/E

Company 2 = 50/100 = (I -E)/E

**==>I2 = (3/2)*E**

so ratio I1: I2 = 16:15

so ratio I1: I2 = 16:15
