Q. In a class, the ratio of students who prefer Math to those who prefer Science is 3:2. If there are 30 students who prefer Science, how many prefer Math?
A.
45
B.
60
C.
30
D.
40
Solution
Let Math = 3x and Science = 2x. Given 2x = 30, x = 15. Therefore, Math = 3x = 3*15 = 45.
Q. The ratio of the speeds of two cars is 3:4. If the faster car travels 120 km in 2 hours, how far does the slower car travel in the same time?
A.
80
B.
90
C.
100
D.
70
Solution
Let the speeds be 3x and 4x. Given 4x = 60 km/h, x = 15. Therefore, slower car's speed = 3x = 3*15 = 45 km/h. Distance = speed * time = 45 * 2 = 90 km.
Q. The ratio of the speeds of two cars is 3:4. If the first car travels 120 km in 2 hours, how far does the second car travel in the same time?
A.
160
B.
180
C.
200
D.
150
Solution
Speed of first car = 120 km / 2 hours = 60 km/h. Let speed of second car = 4x. 3x = 60, x = 20. Therefore, speed of second car = 4*20 = 80 km/h. Distance = speed * time = 80 * 2 = 160 km.
Q. The ratio of the speeds of two cars is 3:4. If the first car travels 120 km, how far does the second car travel?
A.
160
B.
150
C.
180
D.
140
Solution
Let the speed of the first car be 3x and the second car be 4x. The distance traveled is proportional to speed. Therefore, if 3x = 120, then 4x = (4/3)*120 = 160.
