Solution

Let irr be x%
At irr,present value of inflows=present value of outflows.

283215=85500/1.0x+85500/1.0x^2+..............+85500/1.0x^7

283215=85500[1/1.0x+1/1.0x^2+..............+1/1.0x^7]

[1/1.0x+1/1.0x^2+..............+1/1.0x^7]=(283215/85500)

[1/1.0x+1/1.0x^2+..............+1/1.0x^7]=3.312(Approx)

Hence x=irr=23%(Approx).
