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"?

Ans 2:

Class : Class 9
A

Ans 3:

Class : Class 9
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 3:

Class : Class 9

Ans 4:

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 5:

Class : Class 4

Ans 6:

Class : Class 3
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 7:

A

Ans 13:

Class : Class 4
A

Ans 14:

Class : Class 3
The ans is A. They wrote C because no one sits on trucks. But the ans shud be A. Cuz train goes on rails, not on road. The others go on the road, not on rails. Seriously SOF! Why do u give wrong answers? it is not necessary people to sit on trucks!!!

Ans 15:

Class : Class 4

Ans 16:

Class : Class 6
I think the answer is a as it runs on tracks

Ans 17:

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