What approximate value should come in place the of question mark ? in the following question? (You are not expected to calculate the exact value) (180.20 - 59.74) ÷ 40.04 = 79.81 - 61.72 - ? Correct Answer 15
Given expression is,
(180.20 - 59.74) ÷ 40.04 = 79.81 - 61.72 - ?
We can write the given values as:
180.20 ≈ 180 and 59.74 ≈ 60
40.04 ≈ 40 and 79.81 ≈ 80 and 61.72 ≈ 62
Then,
⇒ (180 - 60) ÷ 40 = 80 - 62 - ?
⇒ 120 ÷ 40 = 80 - 62 - ?
⇒ 3 = 80 - 62 - ?
⇒ 3 = 18 - ?
⇒ ? = 18 - 3
⇒ ? ≈ 15
