Class : Class 7
the correct option is d because in all options at least two open figures are in same direction but in option d all are in different direction

Ans 2:

Class : Class 6
D is the option cause in other figures atleast 2 are open in same direction.

Ans 3:

Class : Class 6
I think the answer is (D)

Ans 4:

700-650=(a) 50

Ans 2:

Class : Class 5
Answer is A as we see that bakery B sold 700 cakes and bakery F sold halfway between 700 and 600, which is 650 cakes. now subtract 650 from 700, which is 700-650=50.

hey guys the ans cannot be optiob B because in the second statement it is told that the third side cannot be smaller than the difference of the other two sides that means the third side can be equal or greater than the difference. but it cannot be equal that is why 2nd statement id wrong

Ans 2:

Class : Class 8
Option b

Ans 3:

Class : Class 8
The second statement is true so, answer should be option B

Ans 4:

Class : Class 7

Ans 5:

Class : Class 8
The ans is supposed to be b but the website says it is d. I can’t understand how.

Ans 6:

Class : Class 10

Ans 12:

Class : Class 8
yeah guys !!!! the answer is B.....not D. it is so obvious, the second statement is true....the solution given by the website makes no sense.!

Ans 13:

Class : Class 8
here in the 3rd statement it's written that any 2 sides not the other 2 sides.

Ans 14:

Class : Class 9
Yes,the second statement is true

Ans 15:

Class : Class 8
the second statement is true so, the answer is B

Ans 16:

Class : Class 10
The answer should be b. This sum is there in the IMO Workbook and there the answer is b

Ans 17:

Class : Class 8
The answer is actually supposed to be Option B rather than Option D because the second statement is true

Ans 18:

Class : Class 6
According to their own solution b is a supposed to be correct but the answer given is d???

Ans 19:

Class : Class 8
