Find the approximate value that should come in place of the question mark (?) in the following expression. (You are not expected to calculate the exact value.)
Correct Answer :
8
5
Solution :
The correct option is 8.
We are given the expression:
To find the approximate value of the question mark (?), we can round each term to its nearest convenient whole number:
1. is approximately since 73 = 343.
2. 9.12 is approximately 92 = 81.
3. 11.02 is approximately 11.
Substituting these approximate values back into the expression gives:
Simplifying the left-hand side:
Solving for ?:
Hence, the approximate value that should come in place of the question mark (?) is 8.
