Work: Calculate the value of equation 5/(1+5%)+5/(1+5%)^2+105/(1+5%)^3 .
Question type: Mathematical calculation
Solution:
5/(1+5%)+5/(1+5%)^2+105/(1+5%)^3
=5/1.05+5/(1+5%)^2+105/(1+5%)^3
=5/1.05+5/1.05^2+105/(1+5%)^3
=5/1.05+5/1.05^2+105/1.05^3
=5/1.05+5/1.1025+105/1.05^3
=5/1.05+5/1.1025+105/1.157625
=4.761905+5/1.1025+105/1.157625
=4.761905+4.535147+105/1.157625
=4.761905+4.535147+90.702948
=9.297052+90.702948
=100
Answer:5/(1+5%)+5/(1+5%)^2+105/(1+5%)^3=100
