Question 2 – Think & Reflect (Page 23) For how many km will the fare be ₹ 130? Km travelled 1 2 3 4 5 6 Fare ₹ 25 25 Now, we know that Fare charged = 25 + 15 × (n – 2) For n ≥ 2 We need to find for how many km will the fare be ₹ 130 So, we can put Fare = 130 and find n form the formula Fare charged = 25 + 15 × (n – 2) 130 = 25 + 15 × (n – 2) 130 – 25 = 15 × (n – 2) 105 = 15 × (n – 2) 15 × (n – 2) = 105 (n – 2) = 𝟏𝟎𝟓/𝟏𝟓 n – 2 = 7 n = 9 Thus, fare will be ₹130 for a trip of 9 km
