The correct answer is option 3 i.e 28 and 35

Understanding

Given equation: 28 + 49 - 35 ÷ 7 × 4 = 68

Check the options

Option 1: 4 and 28

After interchanging the equation becomes;

= 4 + 49 - 35 ÷ 7 × 28 

= -87 is not equal to 68.

Hence, option 1 is not the correct answer.

Option 2: 28 and 49

After interchanging the equation becomes;

= 49 + 28 - 35 ÷ 7 × 4 

= 57 is not equal to 68.

Hence, option 2 is not the correct answer.

Option 3: 28 and 35

After interchanging the equation becomes;

= 35 + 49 - 28 ÷ 7 × 4 

= 68 = 68

Hence, option 3 is the correct answer.

Option 4: 49 and 35

After interchanging the equation becomes;

= 28 + 35 - 49 ÷ 7 × 4 

= 35  is not equal to 68.

Hence, option 4 is not the correct answer.
