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.

Ans 13:

Dushyant Singh from Shree Ram Centenial School, Indore
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

ARUNAV from DPS VINDHYANAGAR, VINDHYANAGAR
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 15:

tanmay chaudhry from BAL BHAVAN PUBLIC SCHOOL, New Delhi
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

As air can be compressed and takes up the volume of container, its final volume in the jar will be 400 cm3.

Ans 4:

Keshav Taneja from Wisdom world school, Kurukshetra

I thought it would be C but after profound thinking I realised that the answer would be D

Ans 5:

Hitanshi Behera from Loyola School , Bhubaneswar
Class : Class 4
the question says what is the total volume of AIR in the jar, so as air can be compressed then it should obviously contain 450cm3 and I never heard of glass being flexible in other words the 50cm3 of air in the jar is not going to disappear or fly away so ans is D

Ans 6:

Ridhan from SFS janakpuri, New Delhi
Class : Class 5
air can be compressed and it would be 450 cm3 answer is d

Ans 7:

Tanishka Laha from Euroschool, Bengaluru
Class : Class 5
The volume of the JAR is 400 cm3 . If we insert air in the jar, the VOLUME OF THE JAR will remain the same as it is mentioned that the JAR IS COMPLETELY MADE OF GLASS, which is not flexible. Therefore, the answer is C .......

plz dont be angry. The volume of the glass jar will not change. it will remain the same as it is not flexible. so if we compress air of 50cm3 the volume will decrease. But air occupies the available space. So, the correct answer is C.

Ans 11:

shreyash rawat from podar international school, pune
Class : Class 6
option c is wrong only y has 25ml volume and x has 50ml , z also has 50 ml of volume so , option b is correct

Ans 12:

Hitanshi Behera from Loyola School , Bhubaneswar
Class : Class 4
x=20 and y= 25 read the last line of the question and you will find out

Ans 13:

ARUNAV from DPS VINDHYANAGAR, VINDHYANAGAR
Class : Class 6
Yajat is correct because if you read the question carefully , it is written '30 ml of watter' which means that it was already filled with 30 ml of water. now x=50-30=20cm3 and y =75 - 50 = 25 mlSo correct option is c.
