Answer 1

The cost price of 10 cricket ball = 10xy2

the cost of 3 cricket ball=

$\frac{10xy^{2} \times 3}{10}$

$\frac{30xy ^{2} }{10}$

$3xy ^{2}$

Answer 2

Step-by-step explanation:

Given,

Cost of 10 cricket balls is

$10xy {}^{2}$

[Using Unitary Method]

Therefore, Cost of 1 cricket ball is

$10xy {}^{2} \div 10$

that is equal to

$xy {}^{2}$

So, for 3 cricket balls cost will be

$3 \times xy {}^{2}$

that is

$3xy {}^{2}$

Hope it works for you!
