Given :- Let us assume that the chalan for not wearing a seat belt is Rs 1000 first time and it increases by Rs. 50 each time after that in a month. If a driver is caught 10 times in a month for not wearing a seat belt. Calculate the total fine paid by him.
Answer :-
→ Fine first time = a = Rs.1000
→ increased by = d = Rs.50
→ n = 10 .
so,
→ Total fine = Sn
→ Sn = (n/2)[2a + (n - 1)d]
→ Sn = (10/2)[2*1000 + (10 - 1)50]
→ Sn = 5[2000 + 9*50]
→ Sn = 5(2000 + 450)
→ Sn = 5 * 2450
→ Sn = Rs.12250 (Ans.)
