Direction (41–52): What will come in the place of (?) mark in following question?
Correct Answer :
−29
Solution :
To find the value that comes in place of the question mark (?), we need to evaluate the given mathematical expression step-by-step using the BODMAS rule (Brackets, Orders/Indices/Roots, Division/Multiplication, Addition/Subtraction).
The given expression is:
Step 1: Evaluate the division and the cube root
First, we divide 272 by 4:
Next, we calculate the cube root of 1331. Since , we have:
Substitute these values back into the expression:
Step 2: Perform the multiplication
Multiply 18 by 6:
Substitute this value back into the expression:
Step 3: Perform addition and subtraction
Group the positive numbers together:
Add the numbers:
Subtract 108 from 79:
Thus, the value in place of the question mark (?) is −29.
