Let HCF be x , then LCM = 15x It is given LCM +HCF = 352 x + 15x = 352 ⇒ 16x = 352 x = `352/16` = 22 HCF = 22 and LCM = 15x = 15`xx` 22 = 330 Product of two numbers = Product of their HCF and LCM 110 `xx` other number = 22 `xx` 330 Other number = `(22xx330)/110` = 66
If x 2 – 15x + 51 = 0, then determine the value of (x – 5) + {1/(x – 5)}.
