Answer 1

Answer:

Step-by-step explanation:

Let the Number of Footballs be x

Let the Number of cricket balls be y

Let the Number of Tennis balls  be z

Total balls bought = 100

⇒ x + y + z = 100

  z = 100 - x -y.............................................(1)

Total money spend for Buying 100 balls = ₹100

⇒( ₹15 × x ) + (₹1 × y) + ( ₹0.25 × z ) = ₹100

⇒15x +1y + 0.25z = 100

⇒0.25 ( 60x + 4y + z ) = 100

⇒( 60x + 4y + z ) = 100÷0.25

⇒( 60x + 4y + z ) =400

⇒60x + 4y + 100 - x - y = 400                  From (1)

⇒59x + 3y = 400-100

⇒59x + 3y = 300

⇒59x = 300-3y

⇒x = (300-3y) / 59..................................(2)
