What is this Novemberook. I think it means November Book or is it a typing mistake.

Ans 2:

Class : Class 7
Novemberbook is a typing error. So the ans is D because it is telling 4th Tuesday which is 28th and it is said that just after 28th so the ans is D

Ans 3:

Class : Class 5

Ans 4:

Class : Class 4
[a] is the correct answer

Ans 5:

Class : Class 4

Ans 6:

Class : Class 9
The answer is D because they are saying AFTER 4th Tuesday of November 20XX that means 4th Tuesday is 28th November but after 28th November the date is 29th November .

Ans 7:

Class : Class 9
Novembrook could be a mistake

Ans 8:

Class : Class 5

Ans 9:

Class : Class 4

Ans 10:

Class : Class 4
Novemberook ain't nothin. there is nothin' called like that but is the ans.

Ans 11:

Class : Class 4
They're saying after 4th tuesday that means 29 November. Novemberook could be a mistake.

Ans 12:

Class : Class 5
sof please tell that what is novemberook

Ans 13:

Class : Class 8
[d] is wrong

Ans 14:

Class : Class 5
the correct answer is d

Ans 15:

Class : Class 8
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 16:

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 38:

Class : Class 5
tHE ANSEWR IS c BECAUSE TRUCK IS USED TO TRANSPORT GOODS WHILE THE OTHERS TRANSPORT PASSANGERS
