Question 3 (b) (b) A metro train ticket between two stations is ₹40 for an adult and ₹20 for a child. What is the total cost of tickets: (i) for four adults and three children? (ii) for two groups having three adults each? For (i) for four adults and three children? Price of one adult ticket = Rs 40 Price of one child ticket = Rs 20 Now, Cost of tickets for four adults and 3 children = 4 × Cost of one adult ticket + 3 × Cost of on child ticket = 4 × 40 + 3 × 20 For (ii) for two groups having three adults each? Price of one adult ticket = Rs 40 Now, Cost of tickets for two groups of 3 adults each = 2 × (Cost of 3 adult tickets) = 2 × Cost of 1 adult ticket × 3 = 2 × 40 × 3
