Question

prove that KOLKATA is seven times of LONDON in respect of arrangements of their letters​

Answer 1

Answer: Kolkata=7*London

Step-by-step explanation: Kolkata has 7 letters in which 2a's and 2 k's are indistinguishable.Hence it can be arranged in (7!/2!2!) Ways = 1260

Now, London has 6 letters in which 2 n's and 2 o's are indistinguishable.Hence it can be arranged in (6!/2!2!) Ways = 180 ways

Hence Kolkata/London=1260/180=7

Or, Kolkata=7*London
