Ans 26:

Class : Class 8
E is a symmetrical letter, but in this font it is not because of width on top and bottom

Ans 27:

Class : Class 5
55555!!!!!:(

Ans 28:

Class : Class 7
this doesn't make sense E is also symmetrical

Ans 29:

Class : Class 5
HAS TO BE A

Ans 30:

Class : Class 3
E is not symmetrical because if we see the gap the upper one has a small gap and the lower one has a large gap. That's why there is no symmetriy

Ans 31:

Class : Class 5

Ans 32:

Class : Class 2
No dragonite you are wrong, only 5 letters in the word are symmetrical not 6 : I ,N, A, O, E

Ans 33:

Class : Class 4

Ans 34:

Class : Class 6
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 35:

Class : Class 6
I THINK IT IS A. E IS SYMMETRICAL. But Jyoti is also right

Ans 36:

Class : Class 6
S

Ans 37:

Class : Class 5
Its b!

Ans 38:

Class : Class 6
5- S,I,N,A,O

Ans 39:

Class : Class 6
S

Ans 40:

Class : Class 7
letter E is also an symmetrical on horizontal axis.

Ans 41:

Class : Class 2
Oh E letter is not symmetrical because the gap between to curves is not exactly same focus on E

Ans 42:

Class : Class 5
yes this sof is really bad and mad

Ans 43:

Class : Class 6
S has no line of symmetry, neither horizontal nor vertical ,and it cant be symmetrical by a slanting line.E is also not symmetrical by a horizontal line because the gaps are not equal between them as shown in the picture

Ans 44:

Class : Class 4
EEEEEEEEEEEEEEEEE.....................!!!!!!!!!!???????????

Ans 45:

Class : Class 6
Ans is 4

Ans 46:

Class : Class 6
The answer should be 5!

Ans 47:

Class : Class 5
Sure shot...... all the 5 letters - I,N,A,O,E... All these letters are symmetrical.... Wrong answer uploaded by the website..... Dissapointed....

Ans 48:

Class : Class 5
SOF Olympiad Trainer is wrong. Look carefully. E is symmetrical. I has horizontal line of symmetry

Ans 49:

Class : Class 5
No! Letter E is not symmetrical as the upper side of the E has lesser gap than that of its lower side. Therefore the ans is B.

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.
