What approximate value should come in the place of the question mark '?' in the following question? 156.036 ÷ 12.89 × 12 .06 + ? = 7998.99 ÷ 9.880

What approximate value should come in the place of the question mark '?' in the following question? 156.036 ÷ 12.89 × 12 .06 + ? = 7998.99 ÷ 9.880 Correct Answer 656

Follow BODMAS rule to solve this question, as per the order given below.
Step - 1: Parts of an equation enclosed in Brackets must be solved first, and following BODMAS rule in
the bracket -
Step - 2: Any mathematical 'Of' or 'Exponent' must be solved next.
Step - 3: Next, the parts of the equation that contain 'Division' and 'Multiplication' are calculated.
Step - 4: Last but not the least, the parts of the equation that contain 'Addition' and 'Subtraction' should be
calculated.
Since we need to find out the approximate value, we can write these values to
their nearest integers.
Given expression is

156.036 ÷ 12.89 × 12 .06 + ? = 7998.99 ÷ 9.880

⇒ 156 ÷ 13 × 12 + ? = 8000 ÷ 10

⇒ 12 × 12 + ? = 800

⇒ 144 + ? = 800

⇒ 800 - 144 = ?

∴ ? = 656
