Answer 1

Answer:

Step-by-step explanation:

The formula of inverse proportion is y = k/x, where x and y are two quantities in inverse proportion and k is the constant of proportionality.

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.
