Download Solution PDFWhat approximate value should come in place of the question mark (?) in the following question?
(?) × 17.93 - 23² + √624 = 428 - 195
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFSimplify the right-hand side:
⇒ 428 - 195 = 233
Simplify known values on the left-hand side:
⇒ 23² = 529
⇒ √624 ≈ 24.98 ≈ 25 (approx)
Plug into the equation:
⇒ (?) × 17.93 - 529 + 25 = 233
⇒ (?) × 17.93 - 504 = 233
⇒ (?) × 17.93 = 233 + 504 = 737
⇒ ? = 737 ÷ 17.93 ≈ 737 ÷ 18 ≈ 41
Thus, the correct answer is 41.
