Answer 1

Let the brother be "B", three sisters be "S1", "S2" AND "S3".

Now, let us assume that B had Rs x initially.

As per the question,

After visiting S1, amount with B = x + x - 2000= Rs (2x - 2000).

Similarly, after visiting S2, amount with B = 2 * (2x - 2000) - 2000 = 4x - 6000.

After visiting S3, amount with B = 2 * (4x - 6000) - 2000 = 8x - 14000.

Now, ATP 8x - 14000 =  5000.

or, 8x = 5000 + 14000 = 19000.

or, x = 2375.

Therefore, the brother had with him Rs 2375 at the very beginning.

I, hope the solution is clear to you, if not please ask.
