If you answer every question correctly in the test, the total possible marks are 50*2= <<50*2=100>>100 marks.
If Jose got five questions wrong, he lost 5*2 = <<5*2=10>>10 marks because each question has two marks.
Therefore, Jose scored 100-10 = <<100-10=90>>90 marks on the test.
Meghan scored 20 marks less than that which Jose got, a total of 90-20 = <<90-20=70>>70 marks.
The total marks that Jose and Meghan scored in the test are 70+90 = <<70+90=160>>160
Alisson scored 90-40 = <<90-40=50>>50 marks in the examination, 40 marks less than that which Jose scored on the test.
The total number of marks that the three scored in the test is 160+50 = <<160+50=210>>210
