Question

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

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

Answer 1

The correct option is A $0$

Given that : $20-10=200$
But actually $20\times 10=200$

So, $-$ means $\times$
Given that $8÷4=12$

But actually $8+4=12$
So, $÷$ means $+$
Given that: $6\times 2=4$

But actually $6-2=4$
So, $\times$ means $-$
Thus in the given mathematical language, $-$ means $\times$, $÷$ means $+$, and $\times$ means $-$

So given expression
$=100\times 10-1000+1000÷100-10$
$=1000-1000+10-10=0$
