A) \[3x+4y=27\]
B) \[4x+3y=5\]
C) \[3x+4y=20\]
D) None of these
Correct Answer: C
Solution :
First, identify the variable quantities and let these be x and y. |
Let number of rides = x |
and number of hoopla games played |
by her = y |
Cost of 'x' rides = Rs 3x |
Cost of 'y' hoopla games = Rs 4y |
Total money spent = Rs 20 |
Then, we write the given condition in terms of x and y. |
Let the equation be ax + by + c = 0. |
\[\therefore\]Equation is 3x + 4y = 20 |
