Ans 3:

Class : Class 8
answer is D

Ans 4:

Class : Class 4
right answer is d

Ans 5:

Class : Class 9
I THINK IT ISS D

Ans 6:

Class : Class 1
Somebody explain

Ans 7:

Class : Class 4
it is D as in option B it is written that there are 67 R AROUND Q that means they did not waste time drawing 67 Rs but told us that it is supposed to be 67 Rs and C is also natural hence answer is D

Ans 8:

Class : Class 5
r is the moon. but their is only one moon shown, how can it be d.

Ans 9:

Class : Class 6
The 67 r means 67 moons so the ans d is correct

Ans 10:

Class : Class 8
actually jupiter has 79 moon not 67

Ans 11:

Class : Class 6
yes it should be c

Ans 12:

Class : Class 6

Ans 13:

Class : Class 8
answer is c because Q is earth and R is moon and what is the meaning of 67 R around it .

Ans 14:

Class : Class 7
ccccccc

Ans 15:

Class : Class 5
The answer should be 'C'; option 'B' is incorrect as Jupiter has 79 moons not 67.

Ans 16:

Class : Class 7
Jupiter has 79 moons

Ans 17:

Class : Class 6
Hey how can it be D, mercury is the first planet to the sun, nor it has any moon.It should be C

Ans 18:

Class : Class 7
If Q is Jupiter it has 67 R (or moon) around it. If Q is Earth then R is the moon . Hence the answer is D

Ans 19:

Class : Class 5
the correct answer should be c because earth has one moon while jupiter has 79 moons. And only one moon is shown there is it is obviously earth

Ans 20:

Class : Class 6

Look here there is some problem. The correct answer is not there. Amrit is right. but all are not wrong. Anand and Rajesh are wrong. So, the correct answer will be E (which is not there actually. I made it myself because the correct answer was not there.) Rajesh and Anand.

Ans 2:

Class : Class 4
All are wrong

Ans 3:

Class : Class 5
the correct answer is c because premolars and molars are a set of permanent teeth only.

Ans 11:

Class : Class 4
teeth are made of tough material called enamel .

Ans 12:

Class : Class 7
Rajesh and Anand are wrong I emphasis more about Anand because the tough material in the teeth is it's enamel not the dentine.

Digestion of food takes place in small intestine whereas absorption of water from remaining undigested food takes place in large intestine. Premolars and few molars are not present in milk teeth set.

nknnnk

Ans 18:

Class : Class 6
the answer is not A nor B,C or D

Ans 19:

Class : Class 8
I agree with the solution given. Anand is right as a tooth also includes dentine as well as enamel. If it would have been,'The covering of a tooth is dentine.',it was wrong. Bhavya Jain check the solution.

Ans 20:

Class : Class 7

Ans 21:

Class : Class 4
ans is B

Ans 22:

Class : Class 8
I think the question is wronghow can digestion occur if there is no small intestine? so ans is D

Ans 23:

Class : Class 8
All the teeth have root,crown,neck but their SHAPE is different so Anand is correct.

Ans 24:

Class : Class 8
C is the correct answer because the solution is like that. So i think it is the correct one !
