Question: How much was the total sale of the company ?
Statements:
I. The company sold 8000 units of product A each costing ₹ 25 .
II. This company has no other product line.

Question: How much was the total sale of the company ?

According to given information:
Statements :
I. The company sold 8000 units of product A each costing ₹ 25 .

Revenue from product A = Number of units sold × Cost per unit

Revenue from product A = 8000 × ₹ 25 = ₹ 200,000
II. This company has no other product line.

This statement tells us that product A is the only product the company sells.​​

Combining Statements I and II:
From Statement I, we know the revenue from product A is ₹ 200,000.
From Statement II, we know that product A is the only product the company sells.

Thus, the correct option (d) Both I and II are sufficient.
