Answer 2

The cost of 2 dozens of tennis balls is Rs.840.

Price of 140 tennis balls= Rs 4900

12 units make a dozen so 1 dozen = 12 balls

2 dozens= 24 balls

So the price of 1 tennis ball =Rs 4900/140

Therefore, price of 24 tennis balls= (4900/140)* 24 =Rs. 840.

So, the cost of 2 dozens (24 tennis balls) of tennis balls is Rs 840.
