What approximate value will come in the place of the question mark ‘?’ in the following question? 225.1 × 225.12 × 225.08 × 4.91 × 4.81 × 4.88 × 4.09 × 4.14 = 224.963 × 4 × ?
What approximate value will come in the place of the question mark ‘?’ in the following question? 225.1 × 225.12 × 225.08 × 4.91 × 4.81 × 4.88 × 4.09 × 4.14 = 224.963 × 4 × ? Correct Answer 500
225.1 × 225.12 × 225.08 × 4.91 × 4.81 × 4.88 × 4.09 × 4.14 = 224.963 × 4 × ?
Taking their approx. values
⇒ 225 × 225 × 225 × 5 × 5 × 5 × 4 × 4 = 2253 × 4 × ?
⇒ ? = 2253 × 53 × 42 × 225–3 × 4–1
⇒ ? = 2253–3 × 125 × 42–1
⇒ ? = 2250 × 125 × 41
⇒ ? = 1 × 125 × 4
∴ ? = 500
