Question 1 of 5
1. Question
In the month of July of a certain year, the average daily expenditure of an organisation was Rs. 68. For the first 15 days of the month, the average daily expenditure was85 and for the last 17 days, Rs. 51. Find the amount spent by the organisation on the 15th of the month.
Correct
Ans-c
Standard question requiring good calculation speed. Obviously, the 15th day is being double counted.
Calculations can be reduced by thinking as: Surplus in first 15 days Deficit in last 17 days = 255-289 ® Net deficit of 34. This means that the average is reducing by 34 due to the double counting of the 15th day. This can only mean that the 15th day’s expenditure is Rs. 68 -34= 34.
