Which two signs should be interchanged to make the given equation correct?
2 × 236 - 2 + 36 ÷ 72 = 200
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. ÷ and -.
From option 1: ÷ and -
Given equation is : 2 × 236 - 2 + 36 ÷ 72 = 200
After interchanging the two signs we get,
⇒ 2 × 236 ÷ 2 + 36 - 72 = 200
After using the BODMAS rule we get,
⇒ 2 × (236 ÷ 2) + 36 - 72 = 200
⇒ (2 × 118) + 36 - 72 = 200
⇒ (236 + 36) - 72 = 200
⇒ 272 - 72 = 200
⇒ 200 = 200
LHS = RHS
Hence, the correct answer is ÷ and -.
