What is the deposit? How will you calculate the compound interest without knowing the deposit amount?

The formula for calculating compound interest is >>>>

M = P( 1 + I )^n

Where,

M is the final amount including the principal.

P is the principal amount.

I is the rate of interest per year.

N is the number of years invested

In your question, you haven't mention the Principal amount. Use my above given method to calculate compound interest.

Lets say the amount is $700

m = 700(1+0.12)^10 = 2174.09

This way you can solve the problem.
