Question 26

Which two signs should be interchanged to make the given equation correct?
7 $$\div$$ $$2\times$$ 5 - 4 + 2 = 15

Solution

Given,

7 $$\div$$ $$2\times$$ 5 - 4 + 2 = 15

by checking Option wise , only option 3 satisfy the equation,

i.e $$7+2\times5-4\div2=15$$

= $$7+2\times5-2=15$$

= $$7+10-2=15$$

$$\therefore\ 15=15$$

Hence, L.H.S = R.H.S

Option C is correct.
