Actually D is correct but there is a typing mistake in D4th Tuesday of November 20XX = 28 November. The next day is 29 November. So D is correct not A. There is a typing mistake in D, but that does not mean D is wrong.

Ans 3:

My answer is A as train runs on tracks. It is not necessary that they carry passengers. Why is there no explanation SOF?

Ans 4:

Class : Class 5
The answer has to be A.

Ans 5:

Class : Class 9
answer should be A. Trains can carry goods as well as passengers so the odd one out CANNOT be on the basis of passengers. Please do not give such questions if the answer is not clear

Ans 6:

Class : Class 7

Ans 7:

Class : Class 4
A

Ans 8:

Class : Class 7
It has to be A because train runs on tracks and others run on road.They said " Basis of transport " while on the explanation its written as " Odd one out "

Ans 14:

Class : Class 8
You have to solve on the basis of MODE OF TRANSPORT not MEANS OF TRANSPORT SOF you yourself have given mode of transport is basis but you gave wrong answer! correct answer is A as means of transport includes transport which carry goods, passengers etc. And mode of transport means land, air or water transport. All the options are land transport but train runs on rail and other vehicles(auto rickshaw, truck and bus) run on road So answer is A

Ans 15:

Class : Class 4

Ans 18:

Class : Class 4
my answer is A as train runs on tracks others on road with wheels and can also carry goods not necessary passengers

Ans 19:

Class : Class 5
I chose D because rickshaw runs in A city and the rest do not

Ans 20:

Class : Class 10
SOME TIMES EVEN BUS AND TRAINS CARRY GOODS SO THE ANSWER IS A

Ans 21:

Class : Class 4
