Answers :

1) Answer: E

It is given that,

2) Answer: E

Speed of A on Wednesday = 270/3 =90km/hr

 80%of a +10 = 90

Therefore speed of A on Tuesday = 80km/hr

Distance covered by A on Tuesday= 2.5*80 = 200km

Similarly, distance covered by D on Tuesday = 168.75km

Speed of B on Tuesday = 210/3 =70km/hr

Distance covered by B on Wednesday= 60*4.5 =270km

Similarly distance covered by C on Wednesday= 400km

Required percentage = 368.5/670 ×100 = 55%

3) Answer: A

Let speed of C on Tuesday = 3x

Therefore speed of C on Wednesday= 2x

Total distance covered = 510km

(3x*4.5 + 2x*6) = 510

                        x=20

Therefore speed of C on Monday (2x) =40km/hr

4) Answer: D

There is no relationship between speed of A,C,D on Monday and speed of B,C,D on Wednesday, there solution cannot be established from the given data.

5) Answer: A
