Work: Find the solution of equation 60%-30%-（1+g）/g*8%*（1-60%） = 5% .
Question type: Equation
Solution:Original question:
60 100 | − | 30 100 | − | ( | 1 | + | g | ) | ÷ | g | × | 8 100 | ( | 1 | − | 60 100 | ) | = | 5 100 |
| Multiply both sides of the equation by: | g |
60 100 | g | − | 30 100 | g | − | ( | 1 | + | g | ) | × | 8 100 | ( | 1 | − | 60 100 | ) | = | 5 100 | g |
60 100 | g | − | 30 100 | g | − | 1 | × | 8 100 | ( | 1 | − | 60 100 | ) | − | g | × | 8 100 | ( | 1 | − | 60 100 | ) | = | 5 100 | g |
60 100 | g | − | 30 100 | g | − | 2 25 | ( | 1 | − | 60 100 | ) | − | g | × | 8 100 | ( | 1 | − | 60 100 | ) | = | 5 100 | g |
3 10 | g | − | 2 25 | ( | 1 | − | 60 100 | ) | − | g | × | 8 100 | ( | 1 | − | 60 100 | ) | = | 5 100 | g |
3 10 | g | − | 2 25 | × | 1 | + | 2 25 | × | 60 100 | − | g | × | 8 100 | ( | 1 | − | 60 100 | ) | = | 5 100 | g |
3 10 | g | − | 2 25 | + | 6 125 | − | g | × | 8 100 | ( | 1 | − | 60 100 | ) | = | 5 100 | g |
3 10 | g | − | 4 125 | − | g | × | 8 100 | ( | 1 | − | 60 100 | ) | = | 5 100 | g |
3 10 | g | − | 4 125 | − | g | × | 8 100 | × | 1 | + | g | × | 8 100 | × | 60 100 | = | 5 100 | g |
3 10 | g | − | 4 125 | − | g | × | 2 25 | + | g | × | 6 125 | = | 5 100 | g |
67 250 | g | − | 4 125 | = | 5 100 | g |
Transposition :
67 250 | g | − | 5 100 | g | = | 4 125 |
Combine the items on the left of the equation:
109 500 | g | = | 4 125 |
The coefficient of the unknown number is reduced to 1 :
| g | = | 4 125 | ÷ | 109 500 |
| = | 4 125 | × | 500 109 |
| = | 4 | × | 4 109 |
We obtained :
| g | = | 16 109 |
Convert the result to decimal form :
| g | = | 0.146789 |
