One guy had a habit of spending the money as per the day of the month, for example he will spend $18 on 18th of the month.

Once he spent, $63 in continuous 5 days, **What could be the dates** ?

**What was the first day ?**

**Case 1)**

lets assume all the days were of the same month, in that case

x + (x+1) + (x+2) + (x+3) + (x+4) = 63

5x = 53

x is coming out to be in decimal, which can not be

**Case 2)**

now the other possibility is such that month changes after some days

thus there can be few possibilities

**A) **x + (x+1) + (x+2) + (x+3) + 1 = 63

4x = 56 => x = 14, but 1st cant come after 17th, so it is ruled out

**B)** x + (x+1) + (x+2) + 1 + 2 = 63

3x = 57 => x = 19, but again 1st cant come after 21, so it is ruled out as well

**C)** x + (x+1) + 1 + 2 + 3 = 63

2x = 56 => x = 28, this is possible for the month with 29 days, i.e. February of leap year

**so thee dates were 28,29,1,2,3**
