In the given equations find which of the following interchange of signs/ numbers would make the equations correct:

$10+10÷10-10\times 10=10$

If '$÷$' represents '$+$', '$-$' represents '$\times$', '$+$' represents '$÷$', '$\times$'represents '$-$'. Find out the answer to the following question.

$6\times 20÷5-20+4=?$

$12-16\times 25÷80+10=7$

If '$-$' represented by $\text{'}\times \text{'}, \text{'}÷\text{'}$ represented by $\text{'}+\text{'}, \text{'}+\text{'}$ represented by '$÷$' and '$\times$' represented by '$-$', then $15-12+5\times 9÷12=?$

$10 + 14 \times 20 - 7 ÷ 10 = 40$

If the mathematical operator '$+$' means division, '$-$' means multiplication, '$\times$' means subtraction and '$÷$' means addition. Then the value of:
$11 \times 7 + 21 \times 2 ÷ 2 \times 3 - 4$ is-

1. $\frac{8}{3}$

2. $\frac{4}{3}$

3. $\frac{-4}{3}$

4. $\frac{-8}{3}$

$18 \times 12 / 5 - 10 + 10$

The following equation is incorrect. Which two signs would be interchanged to correct the equation?

$5-16\times 30÷10+4=49$

Choose the group of mathematical signs from the given options that may replace the sign '$*$' in the following equation:

$7 * 7 * 2 * 1=12$

The following equation is incorrect. Which two signs should be interchanged to correct the equation? 

$16-2÷40+4\times 18=40$

In a certain code language $-$ represents $\times , ÷$ represents $+, +$ represents $÷$ and $\times$ represents $-$. 

Find out the answer to the following question.

$16\times 20÷15-4+2=?$

If '$+$' means '$\times$', '$-$' means '$÷$', '$\times$' means '$-$' and  '$÷$' means '$+$' then the value of the given equation is

In a certain code language, '$\times$' represents '$+$', '$÷$' represents '$\times$', '$-$' represents '$÷$' and '$+$' represents '$-$' , Find out the answer to the following question.

$4\times 18÷5-10+8=?$

If '$+$' and '$÷$', '$\times$' and '$-$' are interchanged in the equation $17 ÷ 7 – 27 + 7 \times 3$, then its value will be-

1. $7$
2. $17$
3. $27$
4. $41$
