Work: Calculate the value of equation 400×1500×13%+100×1900/(1+13%)×13%+100×1600×13%+10000×13% .
Question type: Mathematical calculation
Solution:
400×1500×13%+100×1900/(1+13%)×13%+100×1600×13%+10000×13%
=400×1500×13%+100×1900/1.13×13%+100×1600×13%+10000×13%
=400×1500×0.13+100×1900/1.13×13%+100×1600×13%+10000×13%
=400×1500×0.13+100×1900/1.13×0.13+100×1600×13%+10000×13%
=400×1500×0.13+100×1900/1.13×0.13+100×1600×0.13+10000×13%
=400×1500×0.13+100×1900/1.13×0.13+100×1600×0.13+10000×0.13
=600000×0.13+100×1900/1.13×0.13+100×1600×0.13+10000×0.13
=78000+100×1900/1.13×0.13+100×1600×0.13+10000×0.13
=78000+190000/1.13×0.13+100×1600×0.13+10000×0.13
=78000+168141.59292×0.13+100×1600×0.13+10000×0.13
=78000+21858.40708+100×1600×0.13+10000×0.13
=78000+21858.40708+160000×0.13+10000×0.13
=78000+21858.40708+20800+10000×0.13
=78000+21858.40708+20800+1300
=99858.40708+20800+1300
=120658.40708+1300
=121958.40708
Answer:400×1500×13%+100×1900/(1+13%)×13%+100×1600×13%+10000×13%=121958.40708
