Q. A and B can complete a work in 12 days. B and C can complete the same work in 15 days. If A, B, and C work together, how many days will they take to complete the work?
A.
5 days
B.
6 days
C.
7 days
D.
8 days
Solution
Work done by A and B in one day = 1/12. Work done by B and C in one day = 1/15. Let work done by B in one day = x. Then, A's work = 1/12 - x and C's work = 1/15 - x. Solving gives A + B + C = 1/8. Therefore, they will complete the work in 8 days.
Q. A bar graph shows the number of books sold in four months: January (30), February (45), March (25), April (50). What is the average number of books sold per month?
A.
37.5
B.
40
C.
45
D.
35
Solution
Total books sold = 30 + 45 + 25 + 50 = 150. Average = 150 / 4 = 37.5.
Q. A boat can go 30 km upstream in 6 hours. What is the speed of the boat in still water if the speed of the current is 3 km/h?
A.
5 km/h
B.
6 km/h
C.
7 km/h
D.
8 km/h
Solution
Speed upstream = Distance / Time = 30 km / 6 hours = 5 km/h. Speed of boat in still water = Speed upstream + Speed of current = 5 km/h + 3 km/h = 8 km/h.
Q. A boat can travel 48 km downstream in 2 hours. What is the speed of the boat in still water if the speed of the current is 4 km/h?
A.
20 km/h
B.
22 km/h
C.
24 km/h
D.
26 km/h
Solution
Speed downstream = Distance / Time = 48 km / 2 hours = 24 km/h. Speed of boat in still water = Speed downstream - Speed of current = 24 km/h - 4 km/h = 20 km/h.
Q. A boat can travel 60 km downstream in 2 hours. If the speed of the current is 5 km/h, what is the speed of the boat in still water?
A.
25 km/h
B.
30 km/h
C.
35 km/h
D.
40 km/h
Solution
Speed downstream = Distance / Time = 60 km / 2 hours = 30 km/h. Speed of boat in still water = Speed downstream - Speed of current = 30 km/h - 5 km/h = 25 km/h.
Q. A can do a piece of work in 10 days and B can do it in 15 days. If they work together, how long will they take to complete the work?
A.
6 days
B.
8 days
C.
10 days
D.
12 days
Solution
Work done by A in one day = 1/10. Work done by B in one day = 1/15. Together, they do (1/10 + 1/15) = 1/6. Therefore, they will complete the work in 6 days.
