IIFT 2008 Question Paper Question 3

Question 3

All employees have to pass through three consecutive entrance doors to enter into the office and one security guard is deployed at each door. These security guards report to the manager about those who come to office after 10 AM. Ms. Rani is an employee of this office and came late on the annual day. In order to avoid report to the manager she had to pay each security guard half of the money she had in her purse and 2 rupees more besides. She found only one rupee with her at the end. How much money Ms. Rani had before entering the office on the annual day?

Solution

Rani has 1 Rs with her.
Before meeting the third guard she must be having (1+2)*2 = 6 rs.
Before meeting the second guard she must be having (6+2)*2 = 16
Before meeting the first guard she must be having (16+2)*2 = 36
Thus, Ms. Rani had 36 Rs before entering the office on the annual day
