Old gibbous

Class : Class 8
it should be old gibbous.

Ans 5:

Class : Class 5
D Full Moon

Ans 6:

Class : Class 5

Ans 7:

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.

Subject :NSO    Class : Class 4

Ans 1:

Class : Class 4
it can be B [VENUS] BECAUSE IT HAS NO MOONS

Ans 2:

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 3:

Class : Class 4

Ans 4:

Class : Class 8

Ans 5:

Class : Class 8
it can also be like this - Venus-Earth and Mars are inner planets and Jupiter is an outer planet.

Ans 6:

Class : Class 3

Ans 7:

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

Ans 8:

Class : Class 6

Ans 9:

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

Ans 10:

Class : Class 4
d

Ans 11:

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 12:

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

Ans 13:

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

Ans 14:

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 15:

Class : Class 5
Why it cannot be Earth

Ans 16:

Class : Class 3

Ans 17:

Class : Class 7
It is D

Ans 18:

Class : Class 6

Ans 19:

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

Ans 20:

Class : Class 8

Ans 21:

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

Ans 22:

Class : Class 3
Yes the correct answers is D

Ans 23:

Class : Class 4

Ans 24:

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 25:

Class : Class 10
It can be c or d

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 31:

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

Ans 35:

Class : Class 4
