Answer & Explanation

Answers with Explanation:

  1. (b) :

 Average income = (30 + 50 + 40 + 60 + 60)/ 5= 48 lakhs

Total average Profit = [(30 -20) + (50 – 30) + (40 – 30) + ( 60 – 40) + (60 – 35)]/ 5

è 17 lakhs

Ratio = 48 : 17

  1. (a) :

The profit in year 1982 = 30 – 20 = 10 lakhs

The profit in year 1986 = 60 – 35 = 25 lakhs

Increase in profit = 25 – 10 = 15 lakhs

Percentage increase in profit = (15 x 100) / 10 = 150%

  1. (a) :

 Total income = 30 + 50 + 40 + 60 + 60 = 240 lakhs

Total expenditure = 20 + 30 + 30 + 40 + 35 = 155 lakhs

Total income total expenditure = 240 – 155 = 85 lakhs

  1. (c) :

 The profit in year 1983 = 50 – 30 = 20 lakhs

Profit in the year 1984 = 40 – 30 = 10 lakhs

Difference = 20 – 10 = 10 lakhs

  1. (c) :

The average income of the given years

è (30 + 50 + 40 + 60 + 60)/ 5 = 240 /5 = 48 lakhs

There are 3 years ( 1983, 1985, 1986) in which the income is more than the average of the given years.
