Round-trip tickets to a tourist destination are eligible for a discount of 10% on the total fare. In addition, groups of 4 or more get a discount of 5% on the total fare. If the one way single person fare is Rs 100, a group of 5 tourists purchasing round-trip tickets will be charged Rs __________.
850 Rs
Explanation
Round-trip fare per person = 2 × 100 = Rs 200, so 5 people cost 5 × 200 = Rs 1000 before discount. Both discounts (10% round-trip + 5% group-of-4-or-more) apply together on the total fare, giving a combined 15% discount: 1000 × (1 − 0.15) = 1000 × 0.85 = Rs 850.
