Pavani has a certain number of chocolates; she gave one-third of the chocolates to her brother Arjun, one-sixth to her friend Preeti. She was then left with 30 chocolates. What is the sum of the number of chocolates did she give to Arjun and Preeti?
Let the number of chocolates Pavani has be x. x3 are given to Arjun. So now she is left with x−x3 = (2x - 3) chocolates
She gave x6 to Preeti. So, she is left with 2x3 - x6 = 4x6 - x6 = 3x6 = x2 So, x2=30 x=30×2=60
Initially, Pavani has 60 chocolates. She gave 13rd i.e. 603=20 to Arjun. 16th i.e. 10 chocolates to Preeti.
