40/(1+0.1)² + 40/(1+0.1)³ + 50/(1+0.1)³ + 30/(10+0.1)³ = ??

40/(1+0.01) + 40/(1+0.001) + 50/(1+0.001)+ 30/(1000+0.001 )
= 40/1.01 + 40/1.001 + 50/1.001 + 30/1000.001
= 40.4404/1.01101 + 40.4/1.01101 + 50.5/1.01101 / 30/1000.001
= 131.3404/ 1.01101 + 30/1000.001
= 131340.531/1011.01101 + 30.3303/ 1011.01101
= 131370.861/1011.01101
