Short answer
Twin sharing means two people occupy one room, with two single beds or one double, and the advertised per-person price assumes that. A solo traveller pays a single supplement of typically 40 to 70% extra. A third adult sharing usually takes an extra bed at 25 to 35% below the twin rate.
Every package price you see in Indian tour advertising is a twin-sharing price. It is not a discount or an offer; it is the baseline, because hotel rooms are priced per room and the operator divides that cost by two. Booking alone does not halve the room cost, which is what the single supplement recovers.
The extra-bed rate for a third person is lower because most hotels charge a modest add-on for a rollaway rather than a second room. That makes a family of three cheaper per head than a couple, and a family of four typically needs two rooms and loses the advantage.
Watch two details. Twin means two separate beds; if you want a double bed, request it as a preference and understand it is not guaranteed. And a child sharing with two adults without an extra bed, described as child-without-bed, is usually 40 to 50% off the adult rate but means three people in one bed.
