Q If a, b and c are distinct positive real numbers and a 2 b 2 c 2 = 1 , then ab bc ca is (A) less than 1 (B) equal to 1 greater than 1 (D) any real number Ans (A) Sol Since a and b are unequal, $\large \frac{a^2 b^2}{2} > \sqrt{a^2 b^2} $ ( AM > GM for unequal numbers) ⇒ a 2 b 2 > 2ab Similarly , b 2 c 2 > 2bcIf a^2b^2c^2abbcca=0 then prove that a=b=c a² b² c² = ab bc ca On multiplying both sides by '2', it becomes 2 ( a² b² c² ) = 2 ( ab bc ca) 2a² 2b² 2c² = 2ab 2bc 2ca a² a² b² b² c² c² – 2ab – 2bc – 2ca = 0 a² b² – 2ab b² c² – 2bc c² a² – 2ca = 0b2 c2 2 (ab bc ca) = 0 a2 b2 c2 = 2 (ab bc ca)
