Which of the following options is equal to
16 ÷ 4 × 2 – 5 + 1 ?

Correct option is D

Given:
16 ÷ 4 × 2 – 5 + 1 ?
Solution:
According to the question;
=> 16 ÷ 4 × 2 - 5 + 1 = 4 × 2 - 5 + 1
=> 8 - 5 + 1 => 4
Now, let's evaluate each option:
(a) {16 ÷ (4 × 2)} – (5+1) = 2 - 6 = -4
(b) [{16 ÷ (4 × 2)} – 5] +1 = -2 + 1 = -1
(c) {(16 ÷ 4) × 2} – (5+1) = 8 - 6 = 2
(d) [{(16 ÷ 4) × 2} – 5] + 1 = 3 + 1 = 4
Hence option (d) is correct.
