Rakesh and Rajesh together bought 10 balls and 10 rackets

Rakesh and Rajesh together bought 10 balls and 10 rackets. Rakesh spent Rs. 1300 and Rajesh spent Rs. 1500. If each racket costs three times a ball does, then what is the price of a racket?

  1. Rs. 70
  2. Rs. 90
  3. Rs. 210
  4. Rs. 240

Answer

Let cost of racket be Rs. r and cost of ball be Rs. b.

Each racket costs three times a ball does. So,

r = 3b

Total amount spent = Rs. 1300 + Rs. 1500 = Rs. 2800

10r + 10b = 2800

r + b = 280

3b + b = 280

4b = 280

b = 70

r = 3b = 210

The correct option is C.
