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 20:

Ahaan Mittal from Primus Public School, Bengaluru
Class : Class 8
E is a symmetrical letter, but in this font it is not because of width on top and bottom

Ans 21:

Saarth Agrawal from Podar International School , Mumbai
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.

SHOURYA JANA from Birla High School Mukundapur, Kolkata
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 51:

Harshil Jain from DPS, Bangalore
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

Kushagra Chaturvedi from Podar International School Chinchwad, Pune

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.
