S and R are two beehives where S contains more bees than that of R. The honey in these hives is gathered only by the worker - bees and the hive is maintained by the remaining bees. Is the average honey collected per bee in the hive greater in hive R' as compared to hive S?
(1) There are 40% worker - bees in hive R' compared to 30% worker-bees in hive S
(2) In hive S' 5 drops of honey per worker bee is gathered on an average compared to 4 drops of honey per worker bee in hive R'
Let total number of bees in S be x and total number of bees in R be y. Is \(\frac{Honey_R}{y} > \frac{Honey_S}{x}\)?
Statement 1 - Worker bees in R - 40y/100 and worker bees in S - 30x/100
We cannot conclude anything else from this statement, hence this statement is insufficient.
Statement 2 - Honey drops collected in S = 5 * number of worker bees in S and honey drops collected in R = 4 * number of worker bees in R
Cannot calculate total honey collected, hence this statement is insufficient.
Combining both the statements -
Honey drops collected in S = 5 * 30 * x / 100 = 150x/100
Honey drops collected in R = 4 * 40 * y / 100 = 160y/100
Calculating average honey collected -
\(Avg_{S} => \frac{150x/100}{x} = \frac{150}{100}\)
\(Avg_{R} => \frac{160y/100}{y} = \frac{160}{100}\)
\(Avg_{R} > Avg_{S}\) => So, the answer is Yes, both the statements together are sufficient.
