Answer should be A

Ans 4:

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

Ans 5:

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

Ans 6:

Class : Class 5
master . admmin to answer

Ans 7:

Class : Class 5

Ans 8:

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

letter E is also an symmetrical on horizontal axis.

Ans 11:

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

Ans 12:

Class : Class 5
5

Ans 13:

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

Ans 14:

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

Ans 16:

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

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.

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 20:

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

Ans 21:

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 22:

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

Ans 23:

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!

options are wrong.6 is the answer

Ans 34:

Class : Class 8
letter e is also symmetrical

Ans 35:

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

Ans 36:

Class : Class 7
Wrong question the answer is 5

Ans 37:

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 38:

Class : Class 6
Answer is a

Ans 39:

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 40:

Class : Class 5
A , You all are right

Ans 41:

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

Ans 42:

Class : Class 6
S

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

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

Ans 47:

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

Ans 48:

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

Ans 49:

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

Ans 50:

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 51:

Class : Class 5
HAS TO BE A

Ans 52:

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

Ans 53:

Class : Class 3
The answer should be 5!

Ans 54:

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

Ans 55:

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

Ans 56:

Class : Class 6
S

Ans 57:

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

Ans 58:

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 59:

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

Ans 60:

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 61:

Class : Class 5
Its b!

Ans 62:

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.

First Term= square and square root = root 2Second term = square root of (root2 -1)^2 = root2 -1The difference of first and second term = 1

(Master answer) the correct answer is C.

Ans 3:

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 14:

Class : Class 9
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.
