Step-by-step explanation:
A family of 4 members is travelling in railways 3 tier coach another family of 3 members is travelling in 2 tier coach. The combined fare of both the families is Rs. 5100. If first family had 1 member less and the second had 1 member more, the total fare would have been Rs. 300 more. What will be the fare for a complex in railways 2-tier coach for the same journey
Let say 3 Tier one ticket cost = A Rs
& 2 Tier one ticket cost = B Rs
4 A + 3B = 5100
3A + 4B = 5100 + 300
=> 3A + 4B = 5400
4 & eq 1 - 3 * eq 2
=> 16A - 9A = 20400 - 16200
=> 7A = 4200
=> A = 600
4* 600 + 3B = 5100
=> 3B = 2700
=> B = 900
fare for a Person in railways 2-tier coach for the same journey = Rs 900
if all traveled from tier 2 = (4 + 3) * 900 = Rs 6300
