Work: Calculate the value of equation 40/(1+10%)^5+40/(1+10%)^4+60/(1+10%)^3+80/(1+10%)^2+80/(1+10%)-200 .
Question type: Mathematical calculation
Solution:
40/(1+10%)^5+40/(1+10%)^4+60/(1+10%)^3+80/(1+10%)^2+80/(1+10%)-200
=40/1.1^5+40/(1+10%)^4+60/(1+10%)^3+80/(1+10%)^2+80/(1+10%)-200
=40/1.1^5+40/1.1^4+60/(1+10%)^3+80/(1+10%)^2+80/(1+10%)-200
=40/1.1^5+40/1.1^4+60/1.1^3+80/(1+10%)^2+80/(1+10%)-200
=40/1.1^5+40/1.1^4+60/1.1^3+80/1.1^2+80/(1+10%)-200
=40/1.1^5+40/1.1^4+60/1.1^3+80/1.1^2+80/1.1-200
=40/1.610510000000001+40/1.1^4+60/1.1^3+80/1.1^2+80/1.1-200
=40/1.610510000000001+40/1.4641+60/1.1^3+80/1.1^2+80/1.1-200
=40/1.610510000000001+40/1.4641+60/1.331+80/1.1^2+80/1.1-200
=40/1.610510000000001+40/1.4641+60/1.331+80/1.21+80/1.1-200
=24.836853+40/1.4641+60/1.331+80/1.21+80/1.1-200
=24.836853+27.320538+60/1.331+80/1.21+80/1.1-200
=24.836853+27.320538+45.078888+80/1.21+80/1.1-200
=24.836853+27.320538+45.078888+66.115702+80/1.1-200
=24.836853+27.320538+45.078888+66.115702+72.727273-200
=52.157391+45.078888+66.115702+72.727273-200
=97.236279+66.115702+72.727273-200
=163.351981+72.727273-200
=236.079254-200
=36.079254
Answer:40/(1+10%)^5+40/(1+10%)^4+60/(1+10%)^3+80/(1+10%)^2+80/(1+10%)-200=36.079254
