Correct Answer :

Option B

11

Solution :

The correct option is 11.

Let the missing value in place of the question mark (?) be x.

Given equation:

x2+23=85% of 280-94


Step 1: Calculate 85% of 280.

85% of 280=85100×280

=1720×280

=17×14=238


Step 2: Substitute this value back into the right-hand side of the equation.

x2+23=238-94

x2+23=144


Step 3: Solve for x.

x2=144-23

x2=121

x=121=11


Hence, the number that will come in place of the question mark is 11.
