After interchanging the two numbers 80 and 20, what will be the value of the given expression?
7 × 20 ÷ 80 + 3 – 2
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 29
Put 80 where 20 is and 20 where 80 is, then work it out by BODMAS.
After the interchange: 7 × 80 ÷ 20 + 3 – 2
\(7\times80=560\)
\(560\div20=28\)
\(28+3-2=29\)
