Question : In the figure given below, PQ is the diameter of the circle with centre O. If $\angle QOR=100^{\circ}$, then the measure of $\angle PSR$ is:
Option 1: $160^{\circ}$
Option 2: $80^{\circ}$
Option 3: $40^{\circ}$
Option 4: $100^{\circ}$
Correct Answer: $40^{\circ}$
Solution : Given: $\angle POR = 100^\circ$ Now, POQ is a straight line. ⇒ $\angle POR + \angle QOR = 180^\circ$ ⇒ $100^\circ+\angle POR = 180^\circ$ ⇒ $\angle POR = 180^\circ- 100^\circ = 80^\circ$ Theorem: The angle subtended by an arc at the centre is double the

Question : Reshma covers 45 km at a speed of 15 km/hr by bicycle, 80 km at a speed of 40 km/hr by car, and another 6 km at a speed of 2 km/hr on foot. Find her average speed for the whole journey (correct to 2 decimal places).
Option 1: 16.38 km/hr
Option 2: 43.50 km/hr
Option 3: 18.36 km/hr
Option 4: 15.25 km/hr
Correct Answer: 16.38 km/hr
Solution : Reshma covers 45 km at a speed of 15 km/hr by bicycle, 80 km at a speed of 40 km/hr by car, and another 6 km at a speed of 2 km/hr on foot. $\text{Average speed}=\frac{\text{Total distance}}{{\text{Total time}}}$ ⇒ $\text{Average speed}=\frac{45+80+6}{\frac{45}{15}+\frac{80}{40}+\frac{6}{2}}=\frac{131}{3+2+3}=\frac{131}{8}=16.38$ km/hr Hence, the

Question : Two people, A and B, are at a distance of 260 km from each other at 9:00 a.m. A immediately starts moving towards B at a speed of 25 km/hr and at 11:00 a.m., B starts moving towards A at a speed of 10 km/hr. At what time (in p.m.) will they meet each other?
Option 1: 5:00
Option 2: 6:00
Option 3: 6:30
Option 4: 7:00

Question : A part of a journey is covered in 37.5 minutes at 90 km/h and the remaining part in 14 minutes at 80 km/h. The total distance (in km) of the journey is:
Option 1: $76 \frac{5}{12}$
Option 2: $62 \frac{11}{12}$
Option 3: $78 \frac{5}{12}$
Option 4: $74 \frac{11}{12}$
Correct Answer: $74 \frac{11}{12}$
Solution : Given: A part of a journey is covered in 37.5 minutes at 90 km/h and the remaining part in 14 minutes at 80 km/h. We know, Distance = Speed × Time So, first part he covered = $\frac{90}{60}×37.5=\frac{225}{4}$ km And, last part he covered
