Question

Change the negative sentence into an affirmative sentence without changing the meaning
No student in the class is as smart as Sharada.
a) Sharada is the smartest student in the class
b)There are some students in the class as smart as Sharada.
c)Sharada is not the smartest student in the class.
d)No student in the class is as stupid as Sharada.

Answer 1

Hint: The word affirmative itself refers to stating or asserting a fact or information that is highly likely to be true. Negative sentences are those which use any words related to not. Affirmative sentences are those that confirm or assert a fact solemnly without the use of any negative words such as not, don’t, cannot and so on.

Complete answer:
 Now, from the options given above,
Sharada is the smartest student in the class: This sentence is correct in the aspect of the exact meaning as the sentence given in the question. It is valid as an affirmative sentence as well. This is most likely to be the answer.
There are some students in the class as smart as Sharada: This sentence gives a different meaning than that of the question. This implies that she is just one among a bunch of smart students.
Sharada is not the smartest student in the class: the meaning of the sentence is different, it is opposite to that of the given sentence, that is, there are students who are much smarter than her.
No student in the class is as stupid as Sharada: The sentence is negative and the meaning is the exact opposite. This implies Sharada is the stupidest girl in the class.

Hence, Option ‘a’ is the correct answer for the above question.

Note: The first two options may seem possible but, Option b, doesn’t make Sharada an extremity as it did in the question, that is, Option b, counts Sharada as one of the smartest students, not the smartest one.
