Question

If $20-10$ means $200$, $8÷4$ means $12,$ $6\times 2$ means $4,$ $5+5$ means $1$, then $100-10\times 1000÷1000+100\times 10=?$

• A. $0$
• B. $20$
• C. $1000$
• D. $1900$

Answer 1

Answer: (A)

$0$

From the given information, we conclude that

$+$ has to be replaced by $÷$

$-$ by $\times$,

$\times$ by $-$ and

$÷$ by $+$

Now the given expression

$100-10\times 1000÷1000+100\times 10$

It can be written after making appropriate changes,

$100\times 10-1000+1000÷100-10$

Which results in $0$
