The price of a phone was increased by 30% and then again by 30%.
What was the overall percentage increase?

Answer

Let the original price of the phone be P.

After the first increase of 30%, the price becomes P + 0.3P = 1.3P.
After the second increase of 30%, the new price becomes 1.3P + 0.3(1.3P) = 1.3P + 0.39P = 1.69P.
The overall percentage increase is calculated as ((1.69P - P) / P) * 100% = 69%.

Therefore, the overall percentage increase is 69%.
