Answer:
31
Step-by-step explanation:
$23.25 divided by $0.75 is 31.
If he got the jeans for 40% off he paid 60% of the cost for the jeans. With that you can setup an equation.
20 is 60% of what number
is signifies equals and of signifies multiplication
20 = 0.6*x
x = 20/.6
x = 33.33
The regular price of the jeans is $33.33
Partial products are the products obtained during the intermediate stages in order to complete a multiplication process.
Consider 68
43, we have to determine the partial products in this.
Now, 
Expanding this, we get

= 
= 2400 + 180 + 320 + 24
= 2924
Hence,
and
are the required partial products in the product of 68 and 43.
So, Option 3 and 4 are the correct answers.
