P can do a piece of work in 9 days. Q is 50% more efficient than P. The number of days it takes
Q to do the same piece of work is?
What is 2/3 of 9?
2/3 of 9 is 6
To find out how many days it takes for Q to do the same piece of work, we need to calculate Q's efficiency first.
Given that Q is 50% more efficient than P, we know that Q's efficiency is 100% + 50% = 150% of P's efficiency.
Since P can do the work in 9 days, this means that P's efficiency is 100/9 = 11.11% per day.
Now, to find Q's efficiency, we need to calculate 150% of P's efficiency:
Efficiency of Q = 150% * Efficiency of P = 150% * 11.11% = 16.67% per day.
Now, to find the number of days it takes for Q to do the same piece of work, we divide 100% by Q's efficiency:
Number of days for Q = 100% / Efficiency of Q = 100 / 16.67 = 6 days.
So, Q can do the same piece of work in 6 days.
