yes, it is 1500

Ans 3:

Class : Class 7
30000÷20=1500 so B is the answer to this question

Class : Class 5
The Question is not correct

Ans 6:

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.

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.

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 14:

Class : Class 9

Ans 15:

Class : Class 5

Ans 16:

Class : Class 5
The question is unclear and if you count the angles there are 4 angles less than 90 degrees which is wrong i think .

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

Ans 9:

Class : Class 8
yeah guys !!!! the answer is B.....not D. it is so obvious, the second statement is true....the solution given by the website makes no sense.!

Ans 10:

Class : Class 7
Correct answer is b

Ans 11:

Class : Class 9
Yes,the second statement is true

Ans 12:

Class : Class 7
The second statement is true so, answer should be option B

Ans 13:

Class : Class 7
Please check, the questions says DIFFERENCE,

Ans 14:

Class : Class 8
B is correct actually

Ans 15:

Class : Class 8
The ans is supposed to be b but the website says it is d. I can’t understand how.

Ans 16:

Class : Class 8
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 17:

Class : Class 7

Ans 18:

Class : Class 6
According to their own solution b is a supposed to be correct but the answer given is d???

Ans 19:

Ans 21:

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

Ans 24:
