Question

A man lives in an apartment building on the 100th floor. He rides the elevator all the way down to floor 1 every morning then all the way up to floor 100 every evening. The elevator is coin-operated. It costs Rs. 0.25 per floor for floors 1-25, Rs. 0.50 per floor for floors 26-50, Rs. 0.75 per floor for floors 51-75, and Rs. 1.00 per floor for floors 75-100.
How much money does the man spend each day riding the elevator?

Answer 1

Rs.125 per day / Rs. 62.50 one way

---

Rs.0.25* 25 + Rs. 0.5*25 + Rs. 0.75*25 + Rs. 1*25=Rs. 62.5
Rs. 62.5*2= Rs. 125
