Which two signs should be interchanged to make the given equation correct?
756 ÷ 252 + 89 × 180- 63 = 384
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1, i.e. + and ×
Option 1) : + and ×
Given equation is : 756 ÷ 252 + 89 × 180 - 63 = 384
After interchanging the two signs :
⇒ 756 ÷ 252 × 89 + 180 - 63 = 384
After using the BODMAS rule,
⇒ (756 ÷ 252) × 89 + 180 - 63 = 384
⇒ (3 × 89) + 180 - 63 = 384
⇒ 267 + 180 - 63 = 384
⇒ 447 - 63 = 384
⇒ 384 = 384
LHS = RHS
Hence, the correct answer is + and ×.
