Which two numbers (not individual digits) should be interchanged to make the given equation correct?
21 × 5 – 35 + (42 ÷ 7) + 28 = 96
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 35 and 42.
Given equation: 21 × 5 – 35 + (42 ÷ 7) + 28 = 96
On interchanging the numbers:
21 × 5 – 42 + (35 ÷ 7) + 28 = 96
105 - 42 + 5 + 28 = 96
138 - 42 = 96
96 = 96
