Find the value of \(\frac{(67895 \times 67895 - 37895 \times 37895)}{30000}\).

  • A.105790
  • B.75790
  • C.1
  • D.30000

Answer: A

The numerator is in the form \(a^2 - b^2 = (a-b)(a+b)\).

Here a = 67895 and b = 37895.

\(a-b = 67895 - 37895 = 30000\).

\(a+b = 67895 + 37895 = 105790\).

The expression becomes \(\frac{(30000)(105790)}{30000} = 105790\).
