Question

Meenal has some money in her purse. If she adds 51 rs to it becomes four times of the original amount what is the original amount in her purse

Answer 1

Solution:

Let us denote by x the original amount (the money in her purse). According to the data of the problem if she adds 51 rs to the amount of money x in her purse, then the total of money becomes four times the original amount, that is:

Total money = 51+x = 4x

this is equivalent to:

3x= 51

solving for x, we get:

x = 51/3 = 17

So that, we can conclude that the correct answer is:

is the original amount in her purse ​is 17 rs.
