It should be option A- Only 1 As water is liquid, the only change that can be seen is that of the change in shape. it volume will remain the same

Ans 2:

Class : Class 9
A

Ans 3:

Class : Class 9
The answer must be the option "A", as it states so "Farheen filled container X with 100 ml of water." Container Y had just a different shape, and it was also broader, so how can it be the option "C"?

the correct answer is d

Ans 4:

Class : Class 4

Ans 5:

Class : Class 9
Novembrook could be a mistake

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

Ans 8:

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 9:

Class : Class 5

Ans 10:

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 11:

Class : Class 7
Novemberook is a typing mistake. Everyone can see that.

Ans 14:

Class : Class 4

Ans 15:

Class : Class 7
The answer should be A as trains run on track and others run on road.

Ans 16:

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
