Solution

The correct option is C $4$
Given : $54 / 32 = 4, 39 / 42 = 3, 92 / 22 = 7$
$(5 + 4) = 9$ and $(3 + 2) = 5$ . So, $9 - 5 = 4$
$⟹ 54 / 32 = 4$
$∵ (4 + 2) = 6$ and $4 - 2 = 3$ . So, $6 - 3 = 3$
$⟹ 39 / 42 = 3$
$92 - 22 = 70$ and $7 + 0 = 7$
$⟹ 92 / 22 = 7$
Similarly, $(3 + 3) = 6$ and $(2 + 8) = 10$
$∴ 10 - 6 = 4$ .
$∴ 28 / 33 = 4$
Hence, $4$ replaces question mark.
