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, 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: ⇒ 2.25% of (80% of 800) – 1.5% of (60% of 800) =? ⇒ ? = 2.25% of {(80/100) × 800} – 1.5% of {(60/100) × 800} ⇒ ? = 2.25% of 640 – 1.5% of 480 ⇒ ? = (2.25/100) × 640 – (1.5/100) × 480 ⇒ ? = 14.4 - 7.2 ⇒ ? = 7.2 Hence, the required answer is 7.2Related questions
