One says, “Give me a hundred, friend! I shall then become twice as rich as you.” Tell me what is the amount of their respective capital?
Let the capitals be ‘a’and ‘b’ respectively.
Given, one says, “Give me a hundred, friend! I shall then become twice as rich as you.
⇒ a + 100 = 2(b – 100)
⇒ a = 2b – 300
Thus, the capitals can be anything which satisfy the above equations.
