Answer to Problem 6.1.1.1P
x and y are variables, 2 and 3 are their respective constraints.
Explanation of Solution
Given:
Points per question in 1st round=2
Points per question in 2nd round=3
Calculation:
Let total questions in 1st round be x and,
Let total questions in 2nd round be y.
Constraints in x and y are 2 and 3 respectively.
b.
To write an equation
b.
Answer to Problem 6.1.1.1P
Explanation of Solution
Given information:
Total points=60
Points earned for each question in first round=2
Points earned for each question in first round=3
Total question asked=25
Calculation:
According to question,
Total points earned in 1st round=
Total points earned in 2nd round=
Total points earned=points earned in 1st round+ points earned in 2nd round.
Total points earned=
Also,
Total questions=25
Total questions=Number of question asked in 1st+number of question asked in 2nd round
From (1) and (2)
These are the equations.
