Step 1: Read the revenue bars:
The chart gives the values (in Rs. lakh) for 1989 to 1995: Revenue \(120,\ 130,\ 145,\ 165,\ 185,\ 200,\ 220\); Expenditure \(102,\ 110,\ 115,\ 125,\ 135,\ 140,\ 150\); Profit \(20,\ 25,\ 30,\ 40,\ 50,\ 60,\ 70\).
Step 2: Total revenue:
\(120 + 130 + 145 + 165 + 185 + 200 + 220 = 1165\) lakh.
Step 3: Average:
\(\dfrac{1165}{7} \approx 166.4\) lakh, which is approximately Rs. 166 lakh.
Final Answer:
The correct option is (3): Rs. 166 lakh.
