Question : Two stations R and S are 400 km apart from each other. A train leaves from R to S and simultaneously another train leaves from S to R. Both trains meet after 10 hours. If the speed of the first train is 4 km/hr more than the second train, then what is the speed of the slower train?
Option 1: 18 km/hr
Option 2: 26 km/hr
Option 3: 16 km/hr
Option 4: 22 km/hr
Correct Answer: 18 km/hr
Solution : Let the speed of the slower train be $x$ km/hr. Since the speed of the first train is 4 km/hr more than the second train, its speed is ($x$ + 4) km/hr. Distance = Speed$\times$Time For the first train (the faster one), the distance
Question : If in $\triangle \mathrm{ABC}$ and $\triangle \mathrm{DEF}, \frac{A B}{D E}=\frac{B C}{F D}$, then they will be similar when:
Option 1: $\angle B=\angle D$
Option 2: $\angle A=\angle D$
Option 3: $\angle A=\angle F$
Option 4: $\angle B=\angle E$
Correct Answer: $\angle B=\angle D$
Solution :
$\frac{AB}{DE} = \frac{BC}{FD}$ ⇒ $\frac{AB}{BC} = \frac{DE}{FD}$ Angle between $AB$ and $BC$ is $\angle B$ and angle between $DE$ and $FD$ is $\angle D$. $\therefore$ They will be similar when these angles will be equal, i.e, $\angle B = \angle D$ Hence, the
