Directions (1-5): Calculate Quantity I and Quantity II on the basis of the given information then compare them and answer the following questions accordingly.
Q1. Quantity I: How many days A would require to complete the work, working alone.
If two workers A and B working together completed a job in 5 days and if A worked twice as efficiently as he actually did and B worked 1/3 as efficiently as he actually did, the work would have been completed in 3 days.
Quantity II: Arun completes 2/3 of a certain job in 6 days. Lakshya can complete 1/3 of the same job in 8 days and Pulkit can complete 3/4 of the work in 12 days. All of them work together for 4 days and then Arun and Pulkit quit. How long will it take for Lakshya to complete the remaining work alone?

Quantity II: Aman’s share, if Rs. 2250 is divided among three friends Aman, Bijoy and Chandra in such a way that 1/6 th of Aman’s share, 1/4 thof Bijoy’s share and 2/5 th of Chandra’s share are equal.
(a) Quantity I > Quantity II
(b) Quantity I < Quantity II
(c) Quantity I ≥ Quantity II
(d) Quantity I ≤ Quantity II
(e) Quantity I = Quantity II or No relation
Q5. A boat sails down the river for 10 km and then up the river for 6 km. The speed of the river is 1 km/hr.
Quantity I: Speed of boat in still water, if for the whole trip it takes 4 hours.
Quantity II: 4 km/hr
(a) Quantity I > Quantity II
(b) Quantity I < Quantity II
(c) Quantity I ≥ Quantity II
(d) Quantity I ≤ Quantity II
(e) Quantity I = Quantity II or No relation
Direction (6-10): The following questions are accompanied by two statements I and II. You have to determine which statements(s) is/are sufficient/necessary to answer the questions.
(a) Statement I alone is sufficient to answer the question but statement II alone is not sufficient to answer the question.
(b) Statement II alone is sufficient to answer the question but statement I alone is not sufficient to answer the question.
(c) Both the statements taken together are necessary to answer the questions, but neither of the statements alone is sufficient to answer the question.
(d) Either statement I or statement II by itself is sufficient to answer the question.
(e) Statements I and II taken together are not sufficient to answer the question.
