After interchanging the two numbers 10 and 5, what will be the value of the given expression?
13 × 5 ÷ 10 + 6 – 7
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 25
Write the expression with 10 and 5 interchanged, then work it out by BODMAS: multiplication and division from left to right first, then addition and subtraction.
After the interchange: 13 × 10 ÷ 5 + 6 – 7
\(13\times10=130\)
\(130\div5=26\)
\(26+6-7=25\)
