option C is the answer as when you fold each of the other figures (opt. a, b, d), you will get the same cuboid as asked in the question. But in the third option, when you fold the figure along the lines, you will get a cuboid whose one face is missing..... So, this is the explanation :)

answer is D....

Ans 3:

Class : Class 9
both B and C are correct as angle 7.5 can be constructed using compass and ruler and we cant construct a unique triangle with only 3 angles given.

Ans 4:

Class : Class 8
It is meant to be c

Ans 5:

Class : Class 10
Answer is b as the length of sides of triangle are variable and therefore unique triangle cannot be constructed

Ans 6:

Class : Class 9

Ans 7:

Class : Class 8
ans is b.i agree with aditya

Ans 8:

Ans 9:

Class : Class 8
Both B and C are wrong, so one of the options definitely needs do be changes. Someone please look into this.

Ans 11:

Class : Class 10
a is correct (ez)b is INCORRECT (angles can be same but size can vary)c is correct (bisect 60 degrees 3times)answer should be b

Class : Class 10

Ans 14:

Class : Class 8
ya guys the answer is D

Ans 15:

Class : Class 9
Aditya that is the very reason why it will be a unique triangle and option C is correct since it an angle such as that can be created by bisecting 60 degree three times

Ans 16:

Class : Class 8
I mean B

Ans 17:

Class : Class 5
The option b states that a unique triangle is constructed and it is possible to do so. However option c states that we CANNOT construct the angle 7.5. This is false cause it can be constructed by bisecting an angle of 60, three times.

We first need to multiply, then he is telling that he threw 18 of them so, you just need to subtract it from the total number of apples! Then it tells that it is put into 8 boxes so, just divide!
