In a 100 meter race, A covers the distance in 36 seconds and B in 45 seconds. In this race A beats B by:
- 8 m
- 10 m
- 20 m
- 28 m
- c
-
In 100100 metres race, A covers the distance in 3636 seconds and B in 4545 seconds. Clearly, A beats B by (45−36)=9(45−36)=9 seconds.Speed of B =10045=10045 m/sDistance covered by B in 99 seconds =10045×9=10045×9 =20=20 metres.
A train running with a speed of 60km/h crosses a pole in 9 seconds. What is the length of train?
- 100 m
- 120 m
- 140 m
- 150 m
- d
-
Speed=(60×518)m/sec=503m/sec
Lengthofthetrain=(Speed×Time)
Lengthofthetrain=(503×9)m=150m
If average of 5,6,7 and X is 10. What is the value of X?
- 18
- 22
- 28
- 36
- b
-
(5+6+7+X) / 4 =10
(18+X) / 4 =10
18+X=10*4
18+X=40
X=40-18=22
If X% of 60=48 then X =?
- 60
- 80
- 100
- 120
- b
-
x/100 * 60 = 48
x = 48 * 100/60
x = 80
