I THINK IT IS A. E IS SYMMETRICAL. But Jyoti is also right

Ans 2:

Class : Class 5
I agree with Bharat and Jyoti, E is not symmetrical. I know that whenever we write E, like in the font in which I am writing now, it is symmetrical, but as per the question given, the font is different, and so, the letter E is not symmetrical. The curved gaps on top and bottom are very different and they are visible by the naked eye.

Ans 8:

Class : Class 4
how can it be c///

Ans 9:

Class : Class 4
I think it should be option C as , the question is asking how much is left with her when she has baked. She used 5/8 of the flour to bake and 5/8 of 4kg is 2 ½ kg . 4kg take away 2½ kg equals 1½ kg. So it should be option C.

Ans 10:

Class : Class 4
c

Ans 11:

Class : Class 7
ANSWER MUST BE OPTION D , AS WHEN WE SUBTRACT 5/8 FROM 4 THEN WE WILL GET 27/8 WHICH IS EQUAL TO 3 3/8. THE METHOD IS BY DOING CRISS-CROSS MULTIPLICATION.

Ans 12:

Class : Class 5
The correct answer is c

Ans 13:

Class : Class 5

Ans 14:

Class : Class 5
I agree D should be answer. 4 - 5/8

Ans 15:

Class : Class 7
c
