The average revenues of 13 consecutive years of a company is Rs 82 lakhs. If the average of first 7 years is Rs 77 lakhs and that of last 7 years is Rs 89 lakhs, find the revenue for the 7th year.
Total revenues of 13 years of the company = $$82 \times 13$$ = Rs. 1066 lakhs
Total revenue of first 7 years = $$77 \times 7$$ = Rs. 539 lakhs
Total revenue of last 7 years = $$89 \times 7$$ = Rs. 623 lakhs
$$\therefore$$ Revenue of 7th year = (539 + 623) - 1066 = 1162 - 1066
= Rs. 96 lakhs
