The table given below shows the information about bats manufactured by 6 different companies. Each company manufactures only plastic and wooden bats Each company labels these bats as Brand A or Brand B The table shows the number of plastic bats as a percentage of total bats manufactured by each company. It also shows the ratio of wooden bats labeled A and B. Each company manufactured a total of 550000 bats.
P = Sum of wooden bats of Brand B manufactured by S and wooden bats of Brand A manufactured by W.
Q = Difference of Brand B wooden bats and Brand A wooden bats manufactured by U.
What is the value P - Q?
P =Â $$550000\left(0.30\times\frac{7}{22}+0.6\times\frac{5}{11}\right)=227000\ .$$
And , Q =Â $$550000\left(\frac{41}{55}-\frac{14}{55}\right)\times0.25=67500\ .$$
So, P-Q = 159500 .
C is correct choice.
