Answer:
there are fourteen 4-point questions and twenty six 2-point questions.
Step-by-step explanation:
Given : A 40-question test has 108 possible points.
There are m 4-point questions and n 2-point questions.
So , equation for total number of questions in the test :
m + n = 40 | 4n + 2n = 108
Multiplying (i) by 2 , we get
2m + 2n = 80
Subtract (iii) from (ii) , we get
2m = 28
⇒ m = 28/ 2 = 14
Using value of m in (i) , we get
14 + n = 40 ⇒ n = 26
from this we get there are fourteen 4-point questions and twenty six 2-point questions.
hope this helped!
<u>Answer: </u>
Chance bought a surf board for 249. Now it's on sale for 221.10 and 11.20% is the discount.
<u>Solution:
</u>
Step 1:
Bought price= RS.249
Sale price=RS.221.10
Step 2:
Discount = bought price - sales price
Discount = 249 - 221.10
Discount = 27.9
Step 3:
Discount Percent = 
Substitute the value for Discount which we found in step 2 in the above formulae
Discount Percent = 
On simplification, we get
Discount Percent = 11.20%
Result:
Hence from the given data, we got the discount percent is 11.20%
