Working 8 hours a day, Ashu can copy a book in 18 days. How many hours a day should he work so as to finish the work in 12 days?
✓

Answer

If Ashu works for 8 hours daily, he can finish the work in 18 days
If he works for 1 hour daily, he can finish the work in (18 × 8) days or 144 days.
\(\therefore\) Number of hours he should work daily to finish the work in 12 days \(=\frac{144}{12}=12\)
