    Answer:

    Here u go:-

    Answer is 77

    50% of 70 is 35

    40% of 70 is 28

    so, 70-35=35

    70-28=42

    number of students passed in test 1 is 35

    number of students passed in test 2 is 42

    so, total number of students passed is 77.

    Hope it helps!

    And if it does, just thank me to let me know!
