Answer 1

Explanation:

Money in the savings bank account = 80

Present balance = 120

Money increased = 120 - 80 = 40

Percentage increase =

( Increase in measure / Original Value ) X 100

=> ( 40 / 80 ) X 100

=> 50%

Percentage increase = 50%

Answer 2

The increase in amount due to credit is 50%.

Given - Original and new amount

Find - Percentage increase

Solution - To find the percentage increase in account as a result of deposit, the following formula will be used - Percentage increase = change in amount/original amount*100

Now, calculating change in amount by performing subtraction between original and new amount.

Change in amount = New amount - Original amount

Change in amount = 120 - 80

Change in amount = $40

Percentage increase = 40/80*100

Percentage increase = 50%

Hence, the percentage increase in amount is 50%.
