Given : Mary has $2300
Given : Mary decides to withdraw a fixed amount of money every month of the Year.
I'm Solving this Question by Verification of the Given Options
Let us Assume, She Withdraws a fixed amount of $190 every Month
⇒ The Amount she has withdrawn in a year = (190 × 12) = $2280
⇒ The Amount left over will be : (2300 - 2280) = $20
But, we can see that there is no $20 among the 2nd Blank Options. So, This Fixed amount of money cannot be the Answer.
Let us Assume, She Withdraws a fixed amount of $181 every Month
⇒ The Amount she has withdrawn in a year = (181 × 12) = $2172
⇒ The Amount left over will be : (2300 - 2172) = $128
But, we can see that there is no $128 among the 2nd Blank Options. So, This Fixed amount of money cannot be the Answer.
Let us Assume, She Withdraws a fixed amount of $180 every Month
⇒ The Amount she has withdrawn in a year = (180 × 12) = $2160
⇒ The Amount left over will be : (2300 - 2160) = $140
But, we can see that there is no $140 among the 2nd Blank Options. So, This Fixed amount of money cannot be the Answer.
Let us Assume, She Withdraws a fixed amount of $191 every Month
⇒ The Amount she has withdrawn in a year = (191 × 12) = $2292
⇒ The Amount left over will be : (2300 - 2292) = $8
We can see that there is a $8 among the 2nd Blank Options. So, This Fixed amount of money is the Answer.
The Fixed whole-dollar amount of money she takes from her account every month is $191 and she'll have 8 left over.
First Blank : $191
Second Blank : $8
