This is truly unfair. How can you tell simply without any proof that C is the answer? Fix the problem or else it will create harm to the new students who are giving the test. We, the students are losing confidence too because of these types of questions. Please try to understand us also! It is ruining our whole session of olympiads.

Ans 5:

Ans 6:

Class : Class 8
It should be "old gibbous" as in 15 days "no moon" becomes "full moon". The "new crescent moon" is a stage after no moon ,so in 15 days it will become a stage after new moon which is old gibbous.

Ans 7:

Ans 6:

Class : Class 7
Okay everyone, it seems to be that you guys really aren't paying any attention to the whole question.Dear friends, the question says that we have to decide the odd one out on the basis of composition(on what it is made of), not anything else.If you see it this way, Jupiter is the odd one out, not Earth,Venus or Mars, because it is the only planet made of gases, mostly hydrogen. All the other ones are rocky or terrestrial planets, made mostly of rocks and metals, molten or solid.

Ans 7:

Class : Class 3

Ans 8:

Class : Class 4
d

Ans 9:

Class : Class 5

Ans 10:

Class : Class 2
IT'S JUPITER!!!!!!!!!!!!!

Ans 11:

Class : Class 4
WHY NOT B AND D ? VENUS SPINS ANTI-CLOCKWISE???????????????????????

Ans 12:

Class : Class 6
It can also be Earth because it is the only living planet

Ans 13:

Class : Class 7
but venus has no moons therefore option (B)

Ans 14:

Class : Class 7
It is D

Ans 15:

Class : Class 5
only earth consists of water

Ans 17:

Ans 18:

Class : Class 4
d

Ans 19:

Class : Class 4

Ans 20:

Class : Class 9
it can also be like this - Venus-Earth and Mars are inner planets and Jupiter is an outer planet.

Ans 21:

Class : Class 4
but it is d because the question says that we have to say the odd one outby its strature

Ans 22:

Class : Class 4
the answer is (a) because earth is the only Terrestrial planet

Ans 23:

Class : Class 4

Ans 24:

Class : Class 9
d is the correct answer

Ans 25:

Class : Class 4
It can Be A-only red planet, B-rotates anti-clockwise, C-only planet with life, D-largest planet and has hydrogen gas. So it could be all of them

Ans 26:

Class : Class 4

Ans 27:

Class : Class 8
Answer is D because Jupiter is made of dust and gases while Mercury ,Venus and Earth are rocky planets.

Ans 29:

Class : Class 2
D because it is a gaseous planet.

Ans 30:

Class : Class 9
It can be Venus also because it rotates in anti-clockwise direction.

Ans 31:

Class : Class 8
It can be D because Jupiter is the largest planet .

Ans 32:

Class : Class 6
Actually, Jupiter is the right answer. They asked us to find the odd one out in terms of composition or what they are made up of. Since Jupiter is a gas giant with mostly hydrogen and Earth,Venus and mars are rocky planets with many valuable elements, the answer is D.

Ans 33:

Class : Class 8

Ans 34:

Class : Class 7

Ans 35:

Class : Class 6

Ans 36:

Class : Class 6
Jupiter is a planet made of gas but others are not made of gas

Ans 37:

Class : Class 3
Yes the correct answers is D

Ans 38:

Class : Class 4
it can be earth venus and jupiter because earth is only where life exists venus turns anti clock wise jupiter is an outer planet and it is made up of gas

Ans 39:

Class : Class 5
only Jupiter is a gaseous planet ,which is made out of rocks . Jupiter is an outer planet , while earth, Venus and Mercury are inner planets .

Ans 40:

Class : Class 5
it is jupiter because it says that choose the odd one out on the basis of composition which means we have to choose the odd one out on the basis of what they are made up of as earth , venus and mars are rocky planet whereas jupiteris a gaseous planet so it is D

Ans 41:

Class : Class 6

Ans 42:

Class : Class 4

Ans 43:

Class : Class 4
they're asking composition that means of how it was made so D is the wright answer.

Ans 44:

Class : Class 6
It can be B,C and D because Venus does not have any moon and spins anti-clockwise, Earth is the only planet we live and Jupiter because it is a gas giant and is the more than 10 moons.

Ans 45:

Class : Class 8
It can be Venus, Earth or Jupiter.
