After interchanging the two signs × and ÷, what will be the value of the following expression?
20 + 5 ÷ 21 × 3 – 2
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 53
Write × in place of ÷ and ÷ in place of ×, then work it out by BODMAS.
After the interchange: 20 + 5 × 21 ÷ 3 – 2
\(5\times21=105\)
\(105\div3=35\)
\(20+35-2=53\)
