Find out the approximate value which should replace the question mark (?) in the following question. (18.10 × 5.05 – 10.098) – ( ¾ of 15.83) = 33.35 + ?
Find out the approximate value which should replace the question mark (?) in the following question. (18.10 × 5.05 – 10.098) – ( ¾ of 15.83) = 33.35 + ? Correct Answer 35
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 the least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated.
Given Expression,
(18.10 × 5.05 – 10.098) – ( ¾ of 15.83) = 33.35 + ?
We can also write values as:
18.10 ≈ 18, 5.05 ≈ 5, 10.098 ≈ 10, 15.83 ≈ 16, 33.35 ≈ 33
Given expression becomes,
⇒ (18 × 5 – 10) – ( ¾ of 16) = 33 + ?
⇒ (90 – 10) – (3/4 × 16) = 33 + ?
⇒ (80) – (3 × 4) = 33 + ?
⇒ 80 – 12 = 33 + ?
⇒ 68 = 33 + ?
⇒ ? = 68 – 33
⇒ ? ≈ 35
