Answer» The average revenues of 13 consecutive years of a COMPANY is Rs. 78 lakhs. So, the sum of revenues of 13 consecutive years of a company = Rs. 78 × 13 lakhs = Rs. 1014 lakh. The average of first 7 years is Rs. 73 lakhs and that of LAST 7 years is Rs. 85 lakhs. So, the total revenues of first 7 year = Rs. 73 × 7 lakhs = Rs. 511 lakhs. And, the total revenues of last 7 years = Rs. 85 × 7 lakhs = Rs. 595 lakhs. Then, the total revenues of last 6 years = Rs. 1014 – 511 lakhs = Rs. 503 lakhs. ∴ The REVENUE of the 7th year = Rs. 595 – 503 lakhs = Rs. 92 lakhs. |
