    let s = number of people who swam in the shallow end only
    let d = number of people who swam in the deep end only

    since 30 swam in both deep and shallow ends then we eliminate them from the total.
    so 210 - 30 = 180 (total of people who either swam in shallow end only or deep end only)

    and it was given that d = 2 * s

    2 * s + s = 180
    3 * s = 180 then s = 60. And d = 120

    newland2010, your comprehension was wrong! 30 swam in deep and shallow ends (BOTH). The question clearly asks for the number of people who swam in deep end ONLY and shallow end ONLY. my answer was very detailed!
