(b) 32.32

(c) 30.30

(d) Can’t be determined

(e) None of these

(e) None of these

Explanation:

Income of company A in 1999

Let expenditure in  1999 be Rs x crores

0.2x = 34.09 –x

X= 28.40 crores

7. If the expenditure of Company G in 2000 was 20% more than its expenditure in the year 1999 and the Company has earned a profit of 10% in 1999. What was the company income in 1999 in crores Rs.?

(b) 41.25

Explanation:

Expenditure of Company G in 1999

Let its income in 1999 be 1 crores

3.75= I- 37.5

I= 37.5+3.75= Rs.41.25 crores

8. Which of the following Companies had the highest percentage of profit/loss in 2000?

(a) B

(b) C

(c) F

(d) A

(e) None of these

(d) A

Explanation:

Let us compare the ratio,

Profit/Loss=  for variuos companies

A= 10/275

B= 10/32.5

C= -10/45

D= 10/40

E= -5/45

F= -7.5/25

G= 5/45

Now if we compare A, B, C and D obviously 10/27.5 is the grestest, because numerator is the same while denominator is the least in case of A
