conversations.value: Can you explain how to solve this math problem: Mr. Desmond bought three times as many toys for his younger son as he bought for his elder son. If the elder son received 60 toys, how many toys did Mr Desmond buy?

conversations.value: The younger son received three times as many toys as the elder son, which is 3*60 = 180 toys
  Since he bought the toys together, he purchased 180+60 = 240 toys.
