What approximate value should come in place of the question mark (?) in the following question? 24.96% of 2015.76 - √(575.98) = 119.87 × (?)2

What approximate value should come in place of the question mark (?) in the following question? 24.96% of 2015.76 - √(575.98) = 119.87 × (?)2 Correct Answer 2

Given:

24.96% of 2015.76 - √(575.98) = 119.87 × (?)2

Concept Used:

Follow the BODMAS rule according to the table given below:

[ alt="Bodmas" src="//storage.googleapis.com/tb-img/production/21/06/Bodmas.png" style="width: 440px; height: 247px;">

Calculation:

24.96% of 2015.76 - √(575.98) = 119.87 × (?)2

⇒ 25% of 2016 - √(576) = 120 × (?)2

⇒ (25/100) × 2016 - 24 = 120 × (?)2

⇒ (2016/4) - 24 = 120 × (?)2

⇒ 504 - 24 = 120 × (?)2

⇒ 480 = 120 × (?)2

⇒ (?)2 = 480/120

⇒ (?)2 = 4

⇒ ? = 2

∴ 2 will come in place of the question mark ('?').
