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, 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. Given expression is, 15 ÷ 12.5 × 35 + 42.8 × 2.5 = ?2 + 102 ⇒ (15 ÷ 12.5) × 35 + 42.8 × 2.5 = ?2 + 102 ⇒ (1.2 × 35) + (42.8 × 2.5) = ?2 + 102 ⇒ 42 + 107 = ?2 + 102 ⇒ 149 – 100 = ?2 ⇒ ?2 = 49 ∴ ? = 7 |
