The two expressions on either side of the equal sign will have the same value if two numbers on the left-hand side are interchanged and two signs on the right-hand side are interchanged.
What are those two numbers (not digits) and the two signs?
4 × 3 ÷ 6 + 2 – 8 = 10 + 2 × 3 ÷ 5 – 18
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 4 and 8; + and ÷.
Given expression: 4 × 3 ÷ 6 + 2 – 8 = 10 + 2 × 3 ÷ 5 – 18
Option 4) 4 and 8; + and ÷
After interchanging numbers and signs,
⇒ 8 × 3 ÷ 6 + 2 – 4 = 10 ÷ 2 × 3 + 5 – 18
⇒ 8 × 0.5 + 2 – 4 = 5 × 3 + 5 – 18
⇒ 4 + 2 – 4 = 15 + 5 – 18
⇒ 6 – 4 = 20 – 18
⇒ 2 = 2
