In a television game show, the prize money of ₹ 1,00,000 is to be divided equally amongst the winners

Solution:

Let the number of winners be x and the prize amount be y.

If winners increases then, the prize amount will decrease. Hence, they are inversely proportional.

Two numbers x and y are said to be in inverse proportion when an increase in one quantity decreases the other quantity and vice versa.

xy = k or x = (1/y) k

where k is a constant.

x₁y₁ = x₃y₃

1 × 100000 = 4 × y₃

y₃ = 1 × 100000/4

y₃ = 25000

1 × 100000 = 5 × y₄

y₄ = 1 × 100000/5

y₄ = 20000

1 × 100000 = 8 × y₅

y₅ = 1 × 100000/8

y₅ = 12,500

1 × 100000 = 10 × y₆

y₆ = 1 × 100000/10

y₆ = 10000

1 × 100000 = 20 × y₇

y₇ = 1 × 100000/20

y₇ = 5000

Thus, the complete table is shown below:

Number of winners          1 2 4             5             8             10           20        
Prize for winners 1,00,000 50,000 25,000 20,000 12,500 10,000 5,000
