What approximate value should come in the place of a question mark ‘?’ in the following question? 12.5% of 799 + 25% of 399 - 149.89 = ? 

What approximate value should come in the place of a question mark ‘?’ in the following question? 12.5% of 799 + 25% of 399 - 149.89 = ?  Correct Answer 50

Given:

12.5% of 799 + 25% of 399 - 149.89 = ? 

Concept Used:

Follow the BODMAS rule according to the table given below:

Calculation:

Since, we need to find out the approximate value, we can write these values to their nearest integers.

12.5% of 799 + 25% of 399 - 149.89 = ? 

⇒ 12.5% of 800 + 25% of 400 - 150 = ?

⇒ (1/8) × 800 + (1/4) × 400 - 150 = ?

⇒ 100 + 100 - 150 = ? 

⇒ ? = 50

∴ The value of ‘?’ is 50.

Hint

12.5% = 1/8

25% = 1/4
