After making a deposit, puja had $264 in her savings account. she noticed that if she added $26 to the amount originally in the account and doubled the sum, she would get the new amount. how much did she have in the account?

Most people have issues with word problems because they do not go through the words in the question very minutely. It is of immense importance to go through all the data that has been provided in the question.
Let us assume the original amount that Puja had in her account = x dollars
Then from the details already given in the question, we can arrive at the equation
x + 26 + x + 26 = 264
2x + 52 = 264
2x = 264 - 52
2x = 212
x = 212/2
   = 106
From the above deduction we can conclude that the amount Puja originally had in her account was $106. I hope the procedure is clear enough for you to understand.
