Class 10 jkbose math solution chapter 5.1 Question 1 (i)

This question belongs to class 10 Math jkbose from chapter 5, exercise 5.1 and Question 1 and part first.

Question 1. In which of the following situations, does the list of numbers involved make an arithmetic progression, and why?

(i) The taxi fare after each kim when the fare is ₹15 for the first km and ₹8 for each additional km.

Solution: Given: ₹15 for the first km

                  ₹8 for each additional km

Now,

Taxi fare for ist km= 15 (A1)

Taxi fare for 2nd km= 15+8= 23 (A2)

Taxi fare for 3rd km= 15+8+8= 31 (A3)

To check, where it forms an AP (Arithmetic Progression) or not, let's do difference.

Difference = A2 - A1

                    = 15 - 23

                    = 8

Again,

Difference= A3 - A2

                    = 31 - 23

                    = 8

Hence, it forms an AP because the difference is same.
