A binary operation (otimes) is defined by (m otimes n = mn + m – n) on the set of real numbers, for all m, n (in) R. Find the value of 3 (otimes) (2 (otimes) 4).

  • A.
    6
  • B.
    25
  • C.
    15
  • D.
    18
Correct Answer: Option C
Explanation

(m otimes n = mn + m – n)

3 (otimes) (2 (otimes) 4)

2 (otimes) 4 = 2(4) + 2 – 4 = 6

3 (otimes) 6 = 3(6) + 3 – 6  = 15
