Mr.Chaalu while travelling by Ferry queen has travelled the distance one Kilometer more, than the fare he paid per km. Initially he had total amount of Rs.350/- in his wallet. Now he is only left with the minimum sum of (if all the distance travelled by him is in integers)?
Options 1. Rs.26/- 2. Rs.8/- 3. Rs.29/- 4. Can't be determined.
Answer: Rs.8/-359
Need help on how to approach this problem
My Approach: Lets say distance travelled by Chaalu is x. Total distance covered by him is (x+1)
Lets say fare to pay per km is y
So (x+1)*y < 350
So we have to find pair of factors starting from 349/- but not sure upto which number
The Fare/km is N, and the distance traveled is N+1, and the total fare is N*(N+1). When N is 18, the total fare is Rs.342. The remainder is Rs.8.
