Question
If a painter can paint a house in 6 days, how many painters are needed to complete the same job in 2 days?A) 3 painters B) 4 painters C) 6 painters D) 9 painters
Solution
The answer is B) 4 painters. Here's why:
Step 1: Understand the problem. If one painter can paint a house in 6 days, then the speed of one painter is 1 house/6 days.
Step 2: Find out how many houses one painter can paint in one day. This is 1/6 house/day.
Step 3: If we want the house to be painted in 2 days, we need to find out how many painters are needed. This is done by dividing the total time needed by one painter (6 days) by the desired time (2 days).
Step 4: So, 6 days / 2 days = 3 painters.
