Answer 1

Answer:

1960/280*48

196*48/28

196*24/14

196*12/7

28*12

336

Answer 2

Answer:

₹ 336

Step-by-step explanation:

Cost of 280 tennis balls = ₹ 1969

So,

Cost of 1 tennis ball = 1969 ÷ 280

= ₹ 7

1 dozen = 12

4 dozen balls = 12 × 4

= 48 balls

So,

Cost of 4 dozen balls = 7 × 48

= [₹ 336] - Ans.

So,

If 280 balls cost ₹ 1960, so, 4 dozen balls cost ₹ 336.
