GRE Questions and Answers with Explanation

Q:

Three strategies P, Q and R have been initiated for cost cutting in a company producing respectively 20%, 30% and 10% savings. Assuming that they operate independently, what is the net saving achieved ?

A) 49.6%	B) 50.4%
C) 33.67%	D) 66.66%

Answer & Explanation Answer: A) 49.6%

Explanation:

As these three strategies P, Q and R are independent so these will cut cost one after the other.
If initial cost is Rs 100, then
20% cost is cut after initializing strategy P, then cost will remain 80% = 80
further 30% cost is cut after strategy Q, then cost will remain 70% of 80 = 56
further 10% cost is cut after strategy R, then cost will remain 90% of 56 = 50.4

Thus final cost remains 50.4 % of the original cost. Hence net saving is 100 - 50.4 = 49.6 %.

Q:

If watches bought at prices ranging from Rs. 200 to Rs. 350 are sold at prices ranging from Rs. 300 to Rs. 425. What is the greatest possible profit that might be made in selling nine watches ?

A) Rs. 1800	B) Rs. 2000
C) Rs. 2025	D) Rs. 1750

Answer & Explanation Answer: C) Rs. 2025

Explanation:

Profit would be maximum if watches are brought for Rs. 200 and sold for Rs. 425
Profit = Rs. (425 - 200) = Rs. 225
Profit of 9 watches = Rs. 225 x 9 = Rs.2,025.

Q:

Tanks A and B are each in the shape of a right circular cylinder. The interior of tank A has a height of 10 meters and a circumference of 8 meters, and the interior of tank B has a height of 8 meters and a circumference of 10 meters. The capacity of tank A is what percent of the capacity of tank B ?

A) 76%	B) 72%
C) 80%	D) 82%

Answer & Explanation Answer: C) 80%

Explanation:

circumference of A = $2 πr$ = 8 => so r = $\frac{4}{π}$
volume = $π \times {(\frac{4}{π})}^{2} \times 10$ = $\frac{160}{π}$
circumference of B = $2 πr$ = 10 => so r = $\frac{5}{π}$
volume = $π \times {(\frac{5}{π})}^{2} \times 8$ = $\frac{200}{π}$
so ratio of capacities = 160/200 = 0.8
so capacity of A will be 80% of the capacity of B.
