The four points questions are 5.
Step-by-step explanation:
Total points = 50
Total questions = 15
There are 4 points questions and 3 points questions.
Let,
x be the number of 4 points questions
y be the number of 3 points questions
According to given statement;
x+y=15 Eqn 1
4x+3y=50 Eqn 2
Multiplying Eqn 1 by 3
Subtracting Eqn 3 from Eqn 2
As x variable was used for 4 points questions, therefore,
The four points questions are 5.
