Question 55

The average revenues of 9 consecutive years of a company is Rs 76 lakhs. If the average of first 5 years is Rs 71 lakhs and that of last 5 years is Rs 83 lakhs, find the revenue for the 5th year.

Solution

Total revenues of 9 years of the company = $$76 \times 9$$ = Rs. 684 lakhs

Total revenue of first 5 years = $$71 \times 5$$ = Rs. 355 lakhs

Total revenue of last 5 years = $$83 \times 5$$ = Rs. 415 lakhs

$$\therefore$$ Revenue of 5th year = (355 + 415) - 684 = 770 - 684

= Rs. 86 lakhs
