The sum of thrice a number and twice its reciprocal is 97/4. What is the number?1). 92). 103). 84). 7

Answer»

Let the NUMBER be ‘x’.

Given, 3X + 2/x = 97/4

⇒ 3x2 + 2 = 97x/4

12X2 + 8 = 97x

⇒ 12x2 – 97x + 8 = 0

⇒ 12x2 – 96x – x + 8 = 0

⇒ 12x(x – 8) – 1(x – 8) = 0

⇒ (x – 8)(12x – 1) = 0

⇒ x = 8 or x = 1/12

? All the options are whole numbers

∴ x = 8
