Show the answer and the worked solution
Correct answer: C. ₹15,000
Worked solution
- One part = 90,000 / 9 = 10,000. Flights = 50,000, hotels = 30,000, meals = 10,000.
- Flights cost 10% less: a saving of 5,000.
- Meals = 10,000 + 5,000 = ₹15,000.
Answer: ₹15,000.
The idea
Convert the ratio into money once, then treat the adjustments as ordinary arithmetic. Re-deriving the ratio after each change is where these questions become slow.
Shortcut. Stay in parts: a 10% saving on flights' 5 parts is half a part, so meals rise from 1 part to 1.5 parts, and one part is 90,000 ÷ 9 = 10,000: ₹15,000.
Common trap. ₹10,000 is the original meals budget (one ninth of 90,000); converting the ratio correctly and forgetting to add the ₹5,000 flight saving gives it.
