• Rakesh and Rajesh together bought 10 balls and 10 rackets.
• Rakesh spent Rs. 1,300, and Rajesh spent Rs. 1,500.
• Each racket costs three times the price of a ball.

Let:

• The price of one ball is Rs. $x$. -The price of one racket is Rs. $3x$ (since each racket costs three times a ball).

Total cost equations:

• Total cost of 10 balls = $10x$.
• Total cost of 10 rackets = $10 \times 3x = 30x$.
• Combined total cost = Rs. 1,300 (Rakesh) + Rs. 1,500 (Rajesh) = Rs. 2,800.
• Setting up the equation: $10x + 30x = 2800$, $40x = 2800$, $x = 2800 \div 40$, $x = 70$

Price of one racket: $3x = 3 \times 70 =$ Rs. 210.
