It’s quite strange that sometimes there are situations where what you have been studying and practicing comes face to face with what actually occurs in day to day life.
For instance, the mathematical/aptitude problems is something all of us have done at some point or the other in our lives. But sometimes, you tend to create such problems on your own.
Just try and figure this one out if you can.
I go to my office daily via the DND flyway, where I have to pay Rs. 11 as toll for each trip. I have got a member card for that, which I get recharged for 50 trips every time I see the low balance warning on the screen, which displays the balance when you tap the card. But due to the sun or may be out of hurry, I am not able to see the balance every time on the screen. The only thing worrying is when the balance is not a multiple of 11.
And your worst dreams do come true when the inflation rate is so high. So one day when I tapped my card, against the machine, it didn’t show up a multiple of 11 as balance. A few days later I got to know that the rates had gone up by a rupee. After some days of the revised rates, I got my card recharged again for 50 trips. Yesterday, my card balance read Rs. 625.
What I need to figure out is : –
1. Since how many trips have I been paying more toll on the flyway?
2. What was my card balance when I last tapped my card with the older rates?
Can anyone help me out with this? Please mention how you got to the answer as well.
