Correct Answer :

Option A

80

Solution :

To find the value that should replace the question mark (?), we need to simplify the given mathematical equation step-by-step.

The given equation is:

144 6 + 180 5 + 210 7 = ? + 10

Step 1: Simplify each fraction on the left-hand side.

First, divide 144 by 6:
144 6 = 24

Next, divide 180 by 5:
180 5 = 36

Then, divide 210 by 7:
210 7 = 30

Step 2: Substitute the simplified values back into the equation.
24 + 36 + 30 = ? + 10

Step 3: Add the numbers on the left-hand side.
24 + 36 = 60
60 + 30 = 90

So, the equation becomes:
90 = ? + 10

Step 4: Solve for the question mark (?).
Subtract 10 from both sides of the equation:
? = 90 - 10
? = 80

Therefore, the value that comes in place of the question mark is 80.
