Geeta correctly remembers that she took leave after 21st October and before 27th October. Her colleague Seeta took leave on 23rd October, but Geeta was present on that day. If 24th October was a public holiday and 26th October was Sunday, on which day in October did Geeta take leave?
22nd or 25th October.
According to Geeta, 22, 23, 24, 25, 26. According to Seeta, Geeta was present on 23rd. It was a public holiday on 24, and Sunday on 26. So we can rule out 23, 24 and 26. Hence, Geeta had taken leave either on 22nd or 25th October.
