Answer:
for science the number of question is 3
And, for math it would be 5
Step-by-step explanation:
The computation is shown below:
Total questions answered is 8
And, earned points is 13
Let us assume the science question be x
And, the math question be y
Now the equation would be
x + 2y = 13
And the second equation would be
x + y = 8
Now solve the both equation
y = 5
So, the x = 3
hence, for science the number of question is 3
And, for math it would be 5
