I. X and Y together can complete the wok in 8 days.
II. Y and Z together can complete the work in 10 days.
III. X and Z together can complete the work in 12 days.
Options- A. Only I and II
- B. Only II and III
- C. I, II and III
- D. Data is insufficient
- Correct Answer
- I, II and III
Explanation(X + Y)'s 1 day's work = 1/8 ..(i)
(Y + Z)'s 1 day's work = 1/10 ...(ii)
(Z + X)'s 1 day's work = 1/12 ..(iii)
Adding equations i , ii , iii
2(X + Y + Z)'s 1 day's work = 1/8 + 1/10 + 1/12
(X + Y + Z)'s 1 day's work
= 1/2[1/8 + 1/10 + 1/12] ..(iv)
Subtracting Eq. (iii) from Eq. (iv), we get Y's 1 day's work,
Then, required number of days
= 1/Y's 1 day's work - 1. What was the average per annual increase in sales (in $ Billion) from 1994 to 1998?

Correct Answer: 2007
Explanation:
As per given graph, we calculate the difference in two consecutive years import.
In 2003, change in imports = (35 - 30)/35 x 100 = 100/7 = 139/7% fall
In In 2004, change in imports = (40 - 30)/ 50 x 100 = 1/3 x 100 = 331/3% rise
In 2006, change in imports = (55 - 50)/50 x 100 = 10% rise
In 2007, change in imports = (60 - 55/55) x 100 = 91/11% rise
Hence, in 2007 the percentage rise/fall in imports from the previous year is the lowest.
