Question

If '$\times$' means '+', '$÷$' means "-', '+' means '$÷$' and '-' means '$\times$', then what will be the result of the following expression?
$8\times 7-8+40÷2$

• A. $4$
• B. $6\frac{3}{7}$
• C. $13$
• D. $-9$
• E. $7\frac{2}{5}$

Answer 1

The correct option is E $7\frac{2}{5}$

After substituting the symbols in the given expression the new expression will be
$8+7\times 8÷40-2$
= $8+\frac{7}{5}-2$
= $\frac{37}{5}$ or $7\frac{2}{5}$
Hence, option (E) is the correct answer.
