Answer 2

Given,

Cost of 50 basketballs = ₹ 2000

Cost of 10 basketball = ?

Let the cost of 10 basketballs be x

a/q,

50 : 2000 :: 10 : x

$→ 50 \times x = 2000 \times 10$

$→ x = \frac{2000 \times 10}{50}$

$→ x = \frac{20000}{50}$

$→ x = 400$

Hence, Cost of 10 basketballs is ₹ 400.

Or

$Cost \: of \: 50 \: basketballs \: = Rs \: 2000$

$Cost \: of \: 1 \: basketball \: = Rs \: \frac{2000}{50}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 40$

$Cost \: of \: 10 \: basketballs \: = Rs 40 \times 10$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = Rs \: 400$
