Question 95

The sum of twice a number and thrice its reciprocal is 25/2. What is the number?

Solution

Let the number be $$x$$

According to ques, => $$2x + \frac{3}{x} = \frac{25}{2}$$

=> $$\frac{2x^2 + 3}{x} = \frac{25}{2}$$

=> $$4x^2 + 6 = 25x$$

=> $$4x^2 - 25x + 6 = 0$$

=> $$4x^2 - 24x - x + 6 = 0$$

=> $$4x(x - 6) - 1(x - 6) = 0$$

=> $$(4x - 1)(x - 6) = 0$$

=> $$x = 6 , \frac{1}{4}$$

=> Ans - (B)
