Solution

Solution:
Let \( x \) be the cost (in Rs) of one bat. Let \( y \) be the cost (in Rs) of one ball. The cost for 3 bats \( =3 \times x=3 x \) Similarly for 6 balls \( =6 \times y=6 y \) The algebraic representation of the given information is: \( \begin{array}{c} 3 x+6 y=3900 \\ x+3 y=1300 \end{array} \)
