Show the answer and the worked solution

Worked solution

- Total = 15 ÷ 0.20 = ₹75 lakh.
Answer: ₹75 lakh.
The idea
Going from a part back to the whole is a division by the percentage. Multiplying instead is the standard error.
Shortcut. 20% is one-fifth, so the total is 15 × 5 = ₹75 lakh.
Common trap. ₹60 lakh — dividing by 25% (the raw-materials row) instead of rent's 20%; 15 ÷ 0.25 = 60.
