1 Deepak walked at 4 kmph for a certain part of his journey and took an
auto, travelling at 25 kmph for the rest of the journey. If he took 42
minutes for the entire journey, what part of the journey did he walk
given that his average speed for the entire journey was 10 kmph?
**

a. 1 km

b.2 km

c.4 km

d.5 km

Ans: (b).

Speed is 10 kmph; Time is 42 min

So, total distance = 42/60*10= 7 km

Let x km be the walking distance

Therefore, x/4 + (7-x)/25 = 42 min.= 7/10 hours

2 1x= 70-28=42

x= 2 km.

2.9. 17, 88, 176, 847, 1595, ____.

a. 7542

b. 7546

c. 7548

d. 7550

Solution: The digits in each number are reversed and the number so
formed is added to the original number.

17 + 71 = 88; 88 + 88 = 176; 176 + 671 = 847 and so on.

Similarly, 1595 + 5951 = 7546.

3. 10. 28, 38, 49, _____, 70, 77

a. 58

b. 64

c. 66

d. 62

Solution:

28+10, 38+11, 49+13, _____+8, 70+7, 77

The sum of the digits in each number is added to the number to get the
next number in the series.

28 2 + 8 = 10 and 28 + 10 = 38.

38 3 + 8 = 11 and 38 + 11 = 49.

Similarly,, 49 49 + 13 = 62.

4 A fox spots a rabbit 100m away and starts chasing him. The rabbit
realizes this after two minutes and starts running in the opposite
direction to a burrow, which is 40m from where he is right now. Rabbit
covers 1m in 3 leaps whereas the fox covers 3m in 4 leaps. At what
speed the rabbit should run so that he just manages to reach the burrow
if the fox is running at 20 m/min?

a. 24 leaps/min

b. 18 leaps/min

c. 16 leaps/min

d. 180/11 leaps/min.

In two minutes the fox will cover 2*20= 40 metres.

Now, the distance between the fox and rabbit= 100-40= 60 metres.

Now, since they both should reach the burrow simultaneously rabbit will
run 40 metres where as the fox has to run 60+40= 100m.

Time taken by fox to run 100m

= 100/ (20*3/4)= 20/3 minute.

Rabbit has to run 40 metres in 20/3 minute.

Therefore, his speed= 40/(20/3)= 6 metres/min.

As the rabbit covers 1 metre in 3 leaps his speed will be 6*3= 18
