1.	34.5% of 1800 + 12.4% of 1500 = (?)2 + 7261). 272). 93). 814). 162
Answer» 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 in the bracket, the BODMAS rule must be followed, 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 least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated. 34.5% of 1800 + 12.4% of 1500 = (?)² + 726 ⇒ 0.345 × 1800 + 0.124 × 1500 = ?² + 726 ⇒ 807 = ?² + 726 ⇒ ?² = 81 ⇒ ? = 9

Answer»

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 in the bracket, the BODMAS rule must be followed,

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 least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated.

34.5% of 1800 + 12.4% of 1500 = (?)² + 726

⇒ 0.345 × 1800 + 0.124 × 1500 = ?² + 726

⇒ 807 = ?² + 726

⇒ ?² = 81

⇒ ? = 9
