Work: Calculate the value of equation 30/(1+10%)^5+30/(1+10%)^4+30/(1+10%)^3+90/(1+10%)^2+90/(1+10%)-200 .
Question type: Mathematical calculation
Solution:
30/(1+10%)^5+30/(1+10%)^4+30/(1+10%)^3+90/(1+10%)^2+90/(1+10%)-200
=30/1.1^5+30/(1+10%)^4+30/(1+10%)^3+90/(1+10%)^2+90/(1+10%)-200
=30/1.1^5+30/1.1^4+30/(1+10%)^3+90/(1+10%)^2+90/(1+10%)-200
=30/1.1^5+30/1.1^4+30/1.1^3+90/(1+10%)^2+90/(1+10%)-200
=30/1.1^5+30/1.1^4+30/1.1^3+90/1.1^2+90/(1+10%)-200
=30/1.1^5+30/1.1^4+30/1.1^3+90/1.1^2+90/1.1-200
=30/1.610510000000001+30/1.1^4+30/1.1^3+90/1.1^2+90/1.1-200
=30/1.610510000000001+30/1.4641+30/1.1^3+90/1.1^2+90/1.1-200
=30/1.610510000000001+30/1.4641+30/1.331+90/1.1^2+90/1.1-200
=30/1.610510000000001+30/1.4641+30/1.331+90/1.21+90/1.1-200
=18.62764+30/1.4641+30/1.331+90/1.21+90/1.1-200
=18.62764+20.490404+30/1.331+90/1.21+90/1.1-200
=18.62764+20.490404+22.539444+90/1.21+90/1.1-200
=18.62764+20.490404+22.539444+74.380165+90/1.1-200
=18.62764+20.490404+22.539444+74.380165+81.818182-200
=39.118044+22.539444+74.380165+81.818182-200
=61.657488+74.380165+81.818182-200
=136.037653+81.818182-200
=217.855835-200
=17.855835
Answer:30/(1+10%)^5+30/(1+10%)^4+30/(1+10%)^3+90/(1+10%)^2+90/(1+10%)-200=17.855835
