| 1. | \[2x+5y=7\] \[3x+4y=7\] | A. | Inconsistent pair of equations |
| 2. | \[2x+5y=7\] \[4x+10y=7\] | B. | Consistent pair of equations |
| 3. | \[2x+5y=7\] \[4x+10y=14\] | C. | Dependent consistent pair of equations |
A) 1-A, 2-C, 3-B
B) 1-B, 2-C, 3-A
C) 1-B, 2-A, 3-C
D) 1-C, 2-A, 3-B
Correct Answer: C
Solution :
| [c] (1) \[\frac{2}{3}\ne \frac{5}{4}\] \[\therefore \] consistent pair. |
| (2) \[\frac{2}{4}=\frac{5}{10}\ne \frac{7}{7}\] \[\therefore \] inconsistent pair. |
| (3) \[\frac{2}{4}=\frac{5}{10}=\frac{7}{14}\] \[\therefore \]dependent and consistent. |
