Answer 1

I couldn't find anyone that led to the answer 20 but the one that ended closest to 20 is the last one.

Answer 2

Answer: The correct option is,

C. (16−8)×2+4

Explanation:

In option A,

16 - 8 × (2 + 4)

= 16 - 8 × 6

= 16 - 48

= - 32,

In option B,

(16-8) × (2+4)

= 8 × 6

= 48,

In option C,

(16-8) × 2 + 4

= 8 × 2 + 4

= 16 + 4

= 20

In option D,

16 - (8×2 + 4)

= 16 - (16 + 4)

= 16 - 20

= - 4

Therefore, the expression in OPTION C has the value 20.
