Question 6

# What value should come in place of question mark(?) in the following equation?$$360\sqrt?$$ + 4500 = 19700 - 9800

Solution

$$360\sqrt?$$ + 4500 = 19700 - 9800

$$\Rightarrow 360\sqrt? + 4500 = 9900$$

$$\Rightarrow 360\sqrt? = 5400$$

$$\Rightarrow \sqrt? = 15$$

$$\Rightarrow ? = 15^2$$

$$\Rightarrow ? = 225$$
