Question

I had Rs. 1.15 in my wallet in 6 coins, but I found that I could NOT give the change for a rupee, half a rupee, quarter rupee, ten paise or five paise.

Which 6 coins did I have?

Answer 1

15 paise coins -5 and 20 paise coins- 2 its done

Answer 2

According the question, we have to find out number of coins, by which (adding) we can make Rs.1.15 .

To solve this puzzle, we can consider two types of method:-

1) 10 +10+10+10 +50+25=1.15

In this step, if we consider that there were 4 coins of ten paise,

that means :- 10 +10+10+10= 40 paise.

now we will add a coin of 50 paise

∴ the  sum of paise will be = 40 + 50 = 90

at the end let,s we add a coin of 25 paise.

Hence the total sum of money will be :-

90 + 25 = Rs. 1.15

2) 25 +25+25+ 20+10+10= 1.15

In this step, if we consider that there were 3 coins of 25 paise,

that means :- 25+25+25= 75 paise.

now we will add 1 coin of 20 paise

∴ the  sum of paise will be = 75 + 20 = 95

at the end we will add 2 coins of 10 paises

Hence the total sum of money will be :-

75 + 20+10+10 = Rs. 1.15

Ans:- 1) 10 +10+10+10 +50+25=1.15

        2) 25 +25+25+ 20+10+10= 1.15
