If the given interchanges are made in sign and numbers, which one of the four equations would be correct?

Interchanges: Signs: −- and ×\times Numbers: 33 and 66

A. 6−3×2=96 - 3 \times 2 = 9 B. 6×3−4=156 \times 3 - 4 = 15 C. 3×6−4=333 \times 6 - 4 = 33 D. 3−6×8=103 - 6 \times 8 = 10

  1. A.

    A

  2. B.

    B

  3. C.

    C

  4. D.

    D

Answer

D

Explanation

Check option D: 3−6×8=103 - 6 \times 8 = 10 Swap 3↔63 \leftrightarrow 6 and −↔×- \leftrightarrow \times: 6×3−8=18−8=106 \times 3 - 8 = 18 - 8 = 10 LHS = RHS = 10. Thus D is correct.
