A) \[2x+3y=9,3x+5y=18\]
B) \[2x+4y=8,4x+6y=18\]
C) \[2x+3y=9,4x+6y=18\]
D) None of the above
Correct Answer: C
Solution :
Let the cost of 1 pencil be Rs x and that of one eraser be Rs y. |
It is given that Romila purchased 2 pencils and 3 erasers for Rs 9. |
\[\therefore \,\,\,2x+3y=9\] |
It is also given that Sonali purchased 4 pencils and 6 erasers for Rs 18 |
\[\therefore \,\,\,4x+6y=18\] |
Algebraic Representation The algebraic representation of the given situation is |
\[2x+3y=9\] ...(i) |
\[4x+6y=18\] ...(ii) |
