Question

If '-' stands for addition, '+' for multiplication, '$÷$' for subtraction and '$\times$' for division, which one of the following equations is right?

• A. $5-2+12\times 6÷2=27$
• B. $5+2-12÷6\times 2=13$
• C. $5+2-12\times 6÷2=10$
• D. $5÷2+12\times 6-2=13$

Answer 1

The correct option is C $5+2-12\times 6÷2=10$

Using the relations :

$-$ stands for $+,$ $+$ for $\times ,$ $÷$ for $-,$ $\times$ for $÷$

The equations can be solved as follows,

A) $5-2+12\times 6÷2$ means $5+2\times 12÷6-2=5+2\times 2-2=7$

B) $5+2-12÷6\times 2$ means $5\times 2+12-6÷2=10+12-3=19$

C) $5+2-12\times 6÷2$ means $5\times 2+12÷6-2=10+2-2=10$

D) $5÷2+12\times 6-2$ means $5-2\times 12÷6+2=5-2\times 2+2=3$

Thus, only option C is correct.
