Question

from the equation qd=1000-20p workout the quantity demanded for price of rs 5,10,20 and 25​

Answer 1

Qd for price 5 is equal to 900 (it can be calculated as 1000 - 20 \ltimes⋉ 5 = 1000 - 100 = 900).

Qd for price 10 is equal to 900 (it can be calculated as 1000 - 20 \ltimes⋉ 10 = 1000 - 200 = 800).

Qd for price 20 is equal to 900 (it can be calculated as 1000 - 20 \ltimes⋉ 20 = 1000 - 400 = 600).

Hence,

Qd = 900 when p=5

Qd = 800 when p=10

Qd = 600 when p=20

In accordance with the law of demand and equation Qd=1000-20 \ltimes⋉ p, conditional on all else being equal, as the price of a good goes up (from 5 to 20), quantity demanded will go down (from 900 to 600).

Answer 2

900, 800,600, 750

Explanation:

1000 - 20( 5) = 1000 - 100

qd = 900

1000 - 20(10) = 1000 - 200

qd = 800
