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.

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

Ans 24:

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 25:

Class : Class 8
