1) There were some red, blue and green jelly beans in a bag. The number of red jelly beans was 2 1/3 times the number of green jelly beans. The number of blue jelly beans was 0.5 times the total number of red and green jelly beans. When 200 jelly beans were added into the box, the number of green beans became 1.5 times the original number of green jelly beans, the number of red jelly beans was increased by 1/7 and the number of blue beans was increased by 50. Find the total number of jelly beans in the bag in the end.
2) 2/3 of the number of shells Sheba collected is equal to 3/8 of the number of shells Ann and Dick collected together. Ann collected 1/3 as many shells as Dick.
a) What percentage of the total shells did Ann collect?
b) Express the number of shells Dick collected as a percentage of the number of shells Sheba collected, correct to 2 decimal places.
c) If Dick collected 72 shells more than Sheba, how many shells did the 3 children collect in all?
