I know it is 1500, but they should ask the cost of oranges, but they are asking the number of oranges. The amount of money for one orange will help in finding the cost of all oranges, not the number of all oranges.

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

Ans 2:

Class : Class 6
I THINK THE ANSWER IS 'D'

Ans 3:

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

Ans 4:

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

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.

Ans 2:

Class : Class 9
The second statement is true so, answer should be option B

Ans 3:

Class : Class 9

Ans 13:

Class : Class 8
B is correct, SOF should upgrade their answer. This might mislead students.

Ans 14:

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

Ans 15:

Class : Class 10
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 16:

Class : Class 4

Ans 17:

Ans 18:

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

Ans 19:

Class : Class 10

ans is b.there is a technical problem

Ans 24:

Class : Class 7

Ans 25:

B is correct actually

Ans 26:

Class : Class 9
here in the 3rd statement it's written that any 2 sides not the other 2 sides.

Ans 27:

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