A train travels at a speed of 63 km/ph. How
many meter will it travel in 20 minutes.
a) 12000m
b) 18000m
c) 21000m
d) 24000m
Explanation: Speed of train = 63 km/ph
Time = 29 min
Formula: Distance = Speed × Time
20 min = 1/3 hors:
Distance = 63 × 1/3
= 21 Km. = 21×1000 = 21000 m
If a=b then b=a ,for all a, b ∈ R is.......property
a) reflexive
b) symmetric
c) transitive
d) additive
The value of 4 is the solution of equation.
a) 2x = 8
b) x+4 = 0
c) 4x – 6
d) x + 2 = 0
Explanation: To verify this, we substitute x = 4 into the equation:
2(4) = 8 8 = 8
Since the equation is true when x = 4, the value of 4 is indeed a solution of the equation 2x = 8.
Size of an angle is the amount of:
a) Distance between its arms
b) Turn from one arm to the other
c) Distance between its edges
d) Distance between its angles
