Explanation:

Okay, let’s break down the problem step by step:

- The equation is:

?% of (56 ÷ 7) = 36 - 20

- First, solve the division inside the parentheses:

56 ÷ 7 = 8

- Next, subtract on the right side:

36 - 20 = 16

- So the equation is:

?% of 8 = 16

- ?% means we write it as (x/100). Let’s set it up:

(x/100) × 8 = 16

- Solve for x:

x = (16 × 100) / 8

x = 1600 / 8

x = 200

- Let’s look at the options:

1. 180

2. 150

3. 175

4. 200  

5. 96

- The answer is 200, which matches option 4.
