Amanda pours 3/4 of her water into Barbara’s empty bottle. Barbara then pours 3/5 of her water into Charlie’s empty bottle. Charlie then pours 1/2 of his water into David’s empty bottle. If David now has 18 ounces of water, how many ounces does Amanda still have? |

Answer» Solution :- Let TOTAL water in Amanda bottle was x ounces . so, → Amanda pours water in Barbara’s empty bottle = (3/4) of x = (3x/4) ounces . now, → Barbara pours water in Charlie’s empty bottle = (3/5) of (3x/4) = (9X/20) ounces . and, → Charlie pours water in David’s empty bottle = (1/2) of (9x/20) = (9x/40) ounces . A/q, → (9x/40) = 18 → 9x = 40 * 18 → x = 40 * 2 → x = 80 ounces . therefore, → Water Amanda still have = (1/4) of 80 = (1/4) * 80 = 20 ounces . (Ans.)
