Question
If Arjun can complete his work in 28 days by working 4
hours a day, how many hours a day should he work to finish the same work in 16 days?Solution
ATQ,
Let the efficiency of Arjun be 'x' units per hour
Therefore, total work = 4 × 28 × x = 112x units
Let the time he should work to complete the work in 16 days be 'y' hours a day.
ATQ;
112x = 16 × y × x
Or, y = 7
Therefore, he should work for 7 hours a day.
Alternate solution:
Required time = (4 × 28) ÷ 16 = 7 hours
