• A. loss of ₹45
• B. profit of ₹45
• C. profit of ₹90
• D. loss of ₹90

Answer 1

Answer:

B. profit of ₹45

Let’s compute step by step.

Total cost price

• 25 L at ₹45 → $(25 \times 45 = 1125)$

• 15 L at ₹50 → $(15 \times 50 = 750)$

Total cost price:
$1125 + 750 = 1875$

Total quantity

$25 + 15 = 40 \text{ L}$

• Selling price

Sold at ₹48 per liter:
$40 \times 48 = 1920$

Profit / Loss

$1920 - 1875 = 45$

Final Answer:

• $\boxed{\text{INR} 45 \text{ profit}}$
