Question : Direction: An aeroplane covers a distance at a speed of 340 km/h in 8 hours. To cover the same distance in hours, it must travel at what speed?
Option 1: 660 km/h
Option 2: 700 km/h
Option 3: 680 km/h
Option 4: 1020 km/h
Correct Answer: 1020 km/h
Solution : Given: Speed = 340 km/h Time = 8 hrs
Distance = speed × time = 340 × 8 = 2720 km
Time = hrs = 8/3 hrs
Required speed = Distance ÷ Time = 2720 ÷ 8/3 = 2720 × 3/8 = 1020 km/h

Question : The parallel sides of a trapezium are $8\;\mathrm{cm}$ and $4\;\mathrm{cm}$. If the $\mathrm{M}$ and $\mathrm{N}$ are the mid-points of the diagonals of the trapezium, then the length of $\mathrm{MN}$ is:
Option 1: $12\;\mathrm{cm}$
Option 2: $6\;\mathrm{cm}$
Option 3: $1\;\mathrm{cm}$
Option 4: $2\;\mathrm{cm}$
Correct Answer: $2\;\mathrm{cm}$
Solution : In a trapezium, the line segment joining the mid-points of the diagonals is parallel to the bases and its length is half the difference of the lengths of the bases. Given that the lengths of the parallel sides (bases) are $8\;\mathrm{cm}$ and $4\;\mathrm{cm}$. The length
Question : Find the least number divisible by 2, 3, 5, 6, 9, and 18 which is a perfect square.
Option 1: 900
Option 2: 400
Option 3: 144
Option 4: 3600
Correct Answer: 900
Solution : LCM of 2, 3, 5, 6, 9, and 18 = 90 $90 = 2 \times 3 \times 3 \times 5$ As 2 and 5 are not in pairs, we need to multiply 90 by 2 × 5 to make it a perfect square. $\therefore 90

Question : Two trains start from a certain place on two parallel tracks and in the same direction. The speeds of the trains are 45 km/hr and 40 km/hr respectively. The distance between the two trains after 45 minutes will be:
Option 1: 2 km 500 m
Option 2: 2 km 750 m
Option 3: 3 km 750 m
Option 4: 3 km 250 m
Correct Answer: 3 km 750 m
Solution : Given: The speeds of the trains are 45 km/hr and 40 km/hr. The relative speed = (45 – 40) = 5 km/hr = 5 × $\frac{5}{18}$ m/s = $\frac{25}{18}$ m/s Distance travelled after 45 minutes = $\frac{25}{18}$ × 45 × 60 =
