00:01
So the easiest way is to check all of these one by one, right? we simply need to sketch these things out.
00:07
So for the first one, let's draw a market, quantity and price.
00:13
We have demand and supply.
00:16
And in a, we have an increase in demand.
00:19
So here's my increase in demand.
00:21
And this means we're moving up this way.
00:23
So this means in general that the price is going to go up and the quantity is also going to go up.
00:30
Right? and so this one is wrong, right? because it says not price going down and quantity going up.
00:39
So it's not a.
00:41
B, we are thinking about an increase in supply.
00:45
So again, i'm going to sketch these markets.
00:47
Quantity and price, demand and supply.
00:52
Here we have an increase in supply, right? there's my increase in supply.
00:56
So we are moving down this way.
00:58
So this would predict that the.
01:00
Quantity is going to go up and the price is going to go down.
01:04
And the question is saying that the increase in supply is going to lead the price to go down and increase the quantity.
01:12
So this one looks right.
01:14
B is a very plausible answer.
01:16
But let's do the rest just to be totally sure.
01:20
C is a decrease in demand, right? so again, quantity, price, demand, supply.
01:29
We have a decrease in demand.
01:32
There's my decrease in demand.
01:34
So we are going from this equilibrium over to this equilibrium...
