master . admmin to answer

Class : Class 5
HAS TO BE A

## Ans 10:

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 11:

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

## Ans 12:

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

## Ans 13:

Class : Class 5
The answer shoud be B)1 because O has infinite lines of symmetry and also check the solution and stop being dumb.Also E has also 1 line of symmetry but SOF has given the question.Please read the queston carefully.And they have also given an image so 5 would not be the answer.MASTER ANSWER

## Ans 14:

Class : Class 5
1 will be the correct answer because O has infinite lines of symmetry and the question said that how many of the following figures have exactly 2 lines of symmetry. The perfect answer and explanation.

## Ans 15:

Class : Class 6
S and E are symmetrical but in this font it is not

## Ans 16:

Class : Class 7
Wrong question the answer is 5

## Ans 17:

Class : Class 5
MASTER ANSWER!!!!!5 is correct because E also has a horizontal symmetrical line.

## Ans 18:

Class : Class 8
The answer should be 5!

## Ans 19:

Class : Class 8
I THINK IT IS A. E IS SYMMETRICAL. But Jyoti is also right

## Ans 20:

Class : Class 5
0 alphabets of *exact* two lines of symetry

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

## Ans 22:

Answer is a

## Ans 24:

## Ans 26:

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

Class : Class 8
Ans is 4

Class : Class 5

## Ans 29:

Class : Class 6
Answer should be A. S is symmetrical.

## Ans 30:

Class : Class 7
its true.answer should be six !!!

## Ans 31:

Class : Class 5
answer is 4 because they asked for atleast 1 symmetry line

## Ans 32:

Class : Class 7
How r we supposed to know such a small difference E is symetrical

## Ans 33:

Class : Class 3
No dragonite you are wrong, only 5 letters in the word are symmetrical not 6 : I ,N, A, O, E

## Ans 34:

Class : Class 8
E has horizontal line of symmetry

## Ans 35:

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

## Ans 36:

Class : Class 5
Answer should be A

## Ans 37:

Class : Class 7
6 letters are symmetrical. Letters S, I, N, A, O, E

Class : Class 5
Its b!

## Ans 39:

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.

Class : Class 5

## Ans 41:

Class : Class 8
this doesn't make sense E is also symmetrical

## Ans 42:

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 43:

Class : Class 7
I agree with Bharat and Jyoti... e isn't symmetrical

Class : Class 6

## Ans 45:

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

Class : Class 5
5

## Ans 47:

Class : Class 5
A , You all are right

## Ans 48:

Class : Class 8
The answer is clearly 5=I,N,A,O,E

Class : Class 5

## Ans 50:

Class : Class 3
Oh E letter is not symmetrical because the gap between to curves is not exactly same focus on E

## Ans 51:

Class : Class 5
it is 4 i n o and

## Ans 52:

Class : Class 9
options are wrong.6 is the answer

## Ans 53:

Class : Class 5
the answer is b - 5 = i,n,a,o,e

## Ans 54:

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 55:

Class : Class 9
Guys Jyoti mehta from vibgyor high is correct because you see E the gapis lees in one and more in 2 one

## Ans 56:

Class : Class 6
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.
