What approximate value will come in place of question mark (?) in the given questions? (You are not expected to calculate the exact value)
$$2775\times\frac{160}{\sqrt{(?)}}=5550$$
Expression : $$2775\times\frac{160}{\sqrt{(?)}}=5550$$
=> $$\frac{160}{\sqrt{(x)}} = \frac{5550}{2775} = 2$$
=> $$\sqrt{x} = \frac{160}{2} = 80$$
=> $$x = (80)^2 = 6400$$
