Question 43
Which two signs should be interchanged to make the given equation correct?
$$12 \div 2 \times 6 + 4 - 2 = 13$$
Solution
Given Equation :
$$12 \div 2 \times 6 + 4 - 2 = 13$$
The above equation will be correct only interchanging with the sign in option C.
i.e;
$$\therefore\ 12+2\times6\div4-2=13$$Lets solve the equation according to the rule of BODMAS :
$$\therefore\ 12+2\times\frac{6}{4}-2=13$$
$$\therefore\ 12+3-2=13$$
$$\therefore\ 13=13$$
$$\therefore\ L.H.S=R.H.S$$
Hence, Option C is correct.
