#262 - Money puzzle
I saw a Jeans for Rs97. I dont have enough money , so i borrowed Rs50 from my mom and 50 from my dad = Rs100.
I bought the jeans, and had Rs3 change. I gave dad Rs1 and my mom Rs1 and kept the other Rs1 for myself. Now I owe my mum Rs49 and my dad Rs49. 49+49 = 98 + my Rs1 = 99. Where is the missing Rs1?
It was only a trick:
I borrowed my parents (Rs50 + Rs50 = Rs100).
I bought the jeans for Rs97 and i had Rs3 change.
So, the money that i borrowed and bought the jeans are Rs100 (borrowing money)
and the change Rs3 also the borrowing money the jeans is Rs97
Total: Rs97 + Rs3(the change) = Rs100
The money that i used to buy the jeans all i borrowed.
Rs97 is the borrowing money, change: Rs3 also the borrowing money. Rs97 + Rs3 = Rs100

#270 - Maths Handshake Puzzle
At a party, everyone shook hands with everybody else. There were 66 handshakes. How many people were at the party?
12
In general, with n+1 people, the number of handshakes is the sum of the first n consecutive numbers: 1+2+3+ ... + n.
Since this sum is n(n+1)/2, we need to solve the equation n(n+1)/2 = 66.
This is the quadratic equation n2+ n -132 = 0. Solving for n, we obtain 11 as the answer and deduce that there were 12 people at the party.
Since 66 is a relatively small number, you can also solve this problem with a hand calculator. Add 1 + 2 = + 3 = +... etc. until the total is 66. The last number that you entered (11) is n.
