Question
A project budget of ₹4,80,000 is divided between design, build and testing in the ratio 3 : 5 : 4. Half of the testing budget is later moved to build.
What is the final build budget?
Options
- ₹2,00,000
- ₹2,80,000
- ₹3,00,000
- ₹3,20,000
Show the answer and the worked solution
Correct answer: B. ₹2,80,000
Worked solution
- One part = 4,80,000 ÷ 12 = ₹40,000.
- Design = 1,20,000; build = 2,00,000; testing = 1,60,000.
- Half of testing = ₹80,000 moves to build.
- Final build = 2,00,000 + 80,000 = ₹2,80,000.
Answer: ₹2,80,000.
The idea
Convert the ratio into money once, then treat the transfer as ordinary arithmetic. Re-deriving the ratio after the change is slower and error-prone.
Shortcut. Work in parts: build's 5 plus half of testing's 4 is 7 of 12 parts, and 7 × 40,000 = ₹2,80,000.
Common trap. ₹2,00,000 — the build budget before the transfer; half of testing (₹80,000) still has to be added.
