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

Ans 2:

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

Ans 3:

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 4:

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

Ans 3:

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.
