I THINK THE ANSWER IS 'D'

Ans 2:

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 3:

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

Ans 4:

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

Ans 3:

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.

Answer is C as the question says the first and second in the number 94316875 are interchanged, which is 94316857, like that third and fourth digits will be interchanged and so on, which is 49138657. We have to find the third to the left of the seventh digit from the left end after this rearrangement. We have to see the seventh digit from the left end, which is the number 7, now, we have to find the third digit to the left end in which seven is the right end. So, it tells the third number from the right end, which is the number 6.
