Answers & Solutions:
1) Answer (D)
2) Answer (A)
The express train will cover 600 km in 6hrs and will stop fo 21 minutes in total at different stops.
Now, the distance covered by the local train in 6 hours 21 minutes while subtracting the 1 minute for each halt after 25 minutes = 6.35 * 50 – 250/25 = 307.5 km.
Therfore, the correct option is option A.
3) Answer (C)
This can be represented in diagrammatic form as,
Hence, by 30-60-90 theorem
Side opposite to 60 degree angle = $\sqrt{3}$/2 *hypotenuse = $\sqrt{3}$/2 *10 = 8.66 m
Therefore, the correct option is option C.
4) Answer (C)
The aggregate distance covered by squirrel in 1 minute = 6-4 = 2 metres.
So, at the end of 1 minute squirrel will climb 2 metres, at the end of 2 minutes squirrel will climb 4 metres and so on.
At the end of the 57 minute squirrel will have climbed 114 metres.
Now, at the 58th minute it will advance 6 metres more and reach the top.
Therefore, the correct option is option C.
5) Answer (D)
Let the lengths of train be x and y.
Now their speed is (x/27) and (y/17)
Also, they cross each other in 23 seconds.
(x/27) + (y/17) = (x+y)/23
We get (4/621)x = (6/291)y
(x/27)*(4/23) = (102/291)*(y/17)
(x/27)/(y/17) = (102/291)*(23/4)
Ratio of speed = (391/194)
Option D is the correct answer.
6) Answer (D)
The plane left half an hour late i.e it had to cover the same distance in half hour less time.
Now, we know that time = distance/speed
Let the origibal speed of the plane be x.
Now, (1500/x – 1500/x+250) = 0.5
Solving we get x = 750 km/hr.
Hence, the correct answer is option D.
7) Answer (D)
8) Answer (B)
9) Answer (A)
10) Answer (E)
Let the distance between Ram’s office and home = 150d
Then his original speed = $\frac{150d}{30}$ = 5d
Distance that Ram covered at (1/3)rd of original distance = $\frac{150d}{3}$ = 50d
(4/5)th of original speed = $\frac{4}{5} * 5d$ = 4d
Time taken by Ram to cover this distance = $\frac{50d}{4d} = 12.5$minutes
Remaining distance = 150d – 50d = 100d
(2/5)th of original speed = $\frac{2}{5}*5d$ = 2d
Time taken by Ram to cover the remaining distance = $\frac{100d}{2d}$ = 50 minutes
Hence total time taken by Ram = 12.5 + 50 = 62.5 minutes
