Number of students who secured first class in English only is 20

Step-by-step explanation:

  • Step 1: Find the number of students who secured first class in English only.

Total number of students who secured first class in English or Maths, T = 80

Number of students who secured first class in Maths, M = 50

Number of students who secured first class in both English and Maths, EM = 10

⇒ Let the number of students who secured first class in English only be x.

Total students with first class, T = M + EM + x

⇒ 80 = 50 + 10 + x

⇒ 80 = 60 + x

∴ x = 80 - 60 = 20

Answer:

$147,848.5

Step-by-step explanation:

Fixed rate =7.35%

Mortgage Loan= $685,000

Selling price=$782,000

Property tax paid= $14,578.15

Therefore,

Prorated Amount Owed= Outstanding balance on the house + Interest paid on the loan for the year

Prorated Amount Owed=(782500-685000)+7.35% of 685000

=97500+50347.5

=$147,847.5
