The temperature is not specified in the question so generally the farenheit scale, above -40 degrees, is of lower temperature than the Celsius scale.

Ans 3:

Class : Class 7
I think the answer should be A as the temperature is not specified. Lets say P is at 35 degrees celcius and Q is at 35 degrees fahrenheit. 35 degrees celcius = 95 degrees fahrenheit thus proving my point.

Ans 4:

Class : Class 8
at -40 degree both become the same

The temperature is not specified to be -40degrees .Can someone explain how we can get to know that?

Ans 7:

Class : Class 7
why is everyone chatting about random thingsI think the forum is made for students to discuss their answerPlease stop talking about random things

Ans 8:

Class : Class 8
it is not necessary that the temp is -40 if it is not then it will not be equal right

Ans 9:

Ans 10:

Class : Class 7
I think that the answer would be 'c' when both are -40 degree but it is not mandatory to be the readings = - 40 degree it may be more or less than -40 degree. so please look into this!!!

Ans 11:

Class : Class 8
The answer should be that their temperatures may either be same or different from each other.

why are you all talking about stupid information, I cannot understand. This IS TO TALK ABOUT STUDIES!

Ans 14:

Class : Class 7
The answer should be A the website is full of crap

Ans 15:

Class : Class 8
I simply don't understand how they have given C as the answer!For example, if the temperature of P is 32 degree celsius and the temperature of Q is also 32 degree, but fahrenheit, then the temperature of Q will be 0 degree celsius. Therefore, the answer should be A

Ans 4:

Class : Class 6
I think the answer provided is right, since the compass(Red Pointer) is pointing towards her i.e, in the north direction, so she is facing south. Hence for her east will be towards left and then go straight.

Class : Class 6
@Arunav, please don't say these bad comments... It hurts people who have given the wrong answer.

Ans 6:

Class : Class 4
Answer

Ans 7:

Class : Class 6
it's b as when she will turn around she will be facing north and her right is east and when she'll turn the east side is on her left

Ans 8:

Class : Class 9
if we are facing towards north and we have to go to east we must turn towards right and then go to straight.It means that answer they have given us in wrong.

Ans 9:

Class : Class 5
Yes I think it is a as well

Ans 10:

Class : Class 4
Yes the red pointer shows north so she has to go towards east and east is towards right of north answer is wrong the answer should be A

Ans 11:

Class : Class 7

Ans 12:

B

Ans 13:

Class : Class 6
you are wrong ans is bbbbbbbbbbbbbbbbbbbbbbb

Ans 14:

Class : Class 4

Ans 15:

Class : Class 7
EASY MAN ANSWER IS B BECAUSE SHE'S FACING SOUTH AND TO GO EAST YOU TAKE LEFT (IF YOU ARE FACING SOUTH)

Ans 16:

Class : Class 6
kpks, apply mind . it is said that red portion(NORTH) points towards her, which means that she is seeing SOUTH with her eyes. Now , to go eat, if she was seeing north only , she would have to turned right. But as she in facing south, she will have to turn opposite of right i.e - leftso those who are saying ans is a , are mad!!!!!!!

Ans 17:

Class : Class 7
The red portion on the compass always signifies the north direction. So the answer given is wrong.
