Joeli deposited $1000 on 1 January 2011 in an account paying interest of 12% p.a compounded quarterly. He also deposited $800 (on 1 January 2011) in another account which pays 15% p.a. effective interest. Find the time (n) when the two accounts will be equal value if the exact method is used for fractions of an interest period.
