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

Answer is a

Ans 5:

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

Ans 6:

Class : Class 7
no its bstop being dumbits b because only i has two lines of symetryo has infinite lines of symetry this is a master answer stop writing 25 ans all were wrongask sof for help please!

Its b!

S

Ans 9:

Letter E is also symmetrical

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

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

Ans 13:

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 14:

Class : Class 8
Ans is 4

Ans 15:

Class : Class 9
this doesn't make sense E is also symmetrical

Ans 16:

Class : Class 5
master . admmin to answer

Ans 17:

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 18:

Class : Class 6
We need letters with EXACTLY TWO (2) lines of symmetry. Although "O" has infinite lines of symmetry, LOOK CLOSE WITH YOUR EYES PEELED, it is an oval shape, so only 2 lines.

Ans 19:

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

Ans 20:

Class : Class 6
Let's analyze each letter in the word "MOTIVATE" to determine if it has exactly two lines of symmetry:M: This letter has only one line of symmetry, which is a vertical line passing through the middle of the letter.O: This letter has an infinite number of lines of symmetry, as any line passing through its center will divide it into two identical halves.T: This letter has one line of symmetry, which is a horizontal line passing through the middle of the letter.I: This letter has two lines of symmetry, which are a vertical line passing through the middle of the letter and another passing from the top.V: This letter has one line of symmetry, which is a vertical line passing through the top of the letter.A: This letter has one line of symmetry, which is a vertical line passing through the middle of the letter.T: This letter has one line of symmetry, which is a horizontal line passing through the middle of the letter.E: This letter has zero lines of symmetry, as there is a small gap between the first top two horizontal lines and a big gap between the last two horizontal lines.Also, in the question, SOF has clearly mentioned "which have exactly two lines of symmetry" This line proves that we need to find such an answer which supports and goes in agreement with the question.Therefore, only one letter in the word "MOTIVATE" have exactly two lines of symmetry, which is the "I" letter.I request SOF to correct the answer and give us the missing mark.

Ans 21:

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

Ans 22:

Class : Class 3
The answer should be 5!

Ans 23:

Class : Class 6

Ans 24:

Class : Class 5
O has infinate lines of symmetry, however in the question it has given „EXACTLY 2 lines of symmetry“

Ans 25:

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 26:

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

Ans 27:

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

Ans 28:

Class : Class 5
how is N symmetrical!!!!!

Ans 29:

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

Ans 30:

Class : Class 5
Answer should be A

Ans 31:

Class : Class 9
I THINK IT IS A. E IS SYMMETRICAL. But Jyoti is also right

Ans 32:

Class : Class 5
it is 4 i n o and

Ans 33:

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

Ans 34:

Class : Class 7
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 35:

Class : Class 7
Wrong question the answer is 5

Ans 36:

Class : Class 5

Ans 37:

Class : Class 8
E has horizontal line of symmetry

Ans 38:

Class : Class 5
A , You all are right

Ans 39:

Class : Class 7
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.

Ans 40:

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

Ans 41:

Class : Class 5
HAS TO BE A

Ans 42:

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

Ans 43:

Class : Class 7
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

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 49:

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

Ans 50:

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

Ans 51:

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

Ans 52:

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

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.
