» Explain it
D
Total income of companies M and N together = \$ (35 + 50) = \$ 85 US million

Total expenditure of companies M and N together = \$ (35 + 50) = \$ 85 US million

Thus, there was neither loss nor profit for companies M and N together.

Hence, option D is correct.

2

» Explain it
A
Total income of all five companies = \$ (35 + 50 + 40 + 40 + 50) US million = \$ 215 US million

Total expenditure of all five companies = \$ (45 + 40 + 45 + 30 + 45) US million = \$ 205 US million

 ∴    Profit % = 215 – 205 × 100 205

= 4.88% ≈ 5%

Hence, option A is correct.

= 33.33% i.e. 33.3% profit

» Explain it
D
Let the expenditure of 2010 be x. then,

120% ≡ 45

100% ≡ x

By the cross multiplication, we get

 x = 45 × 100 = 75 = 37.5 120 2

Let company income I with 10% profit. Then,

100% ≡ 37.5

110% ≡ I

By the cross multiplication, we get
 I = 37.5 × 110 = 41.25 100

Hence, option D is correct.

5
If the income of company Q in 2011 was 10% more than its income in 2010 and the company had earned profit of 20% in 2010, then its expenditure in 2010 (in million US \$) was
» Explain it
B
Let the income of 2010 be x, then

110% ≡ 40

100% ≡ x

By the cross multiplication, we get

 x = 40 × 100 = 400 = 36.36 110 11

Now, company earned 20% profit on 36.36

So, 120% ≡ 36.36

100% ≡ x

 x = 36.36 × 100 = 30.30 120

Hence, option B is correct.
