B

Class : Class 5

Class : Class 8
yes, it is 1500

Class : Class 6

## Ans 14:

Class : Class 6
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.

Class : Class 5

Class : Class 5

D

Class : Class 9

## Ans 13:

Class : Class 3
how the answer is D?

Subject :IMO    Class : Class 6

## Ans 1:

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

## Ans 2:

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

## Ans 3:

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

## 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

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.
