Maths Heuristics Question 2 (Deepika, Rhea and Jun Jie)

Aaron,Ben and Charles shared 110 marbles.Ben received twice as many marbles as Aaron.Charles received 10 more marbles than Aaron.How many marbles did each boy receive?

Solution:

Let the no. of marbles that Aaron has be x.

Aaron has x marbles.

Ben has x*2=2x marbles.

Charles has x+10 marbles.

Total number of marbles would be x+2x+x+10 marbles which equals to 4x+10 marbles.

110 marbles equals to 4x+10 marbles

4x=100 marbles

x=100/4= 25

25*2=50

25+10=35

Aaron had 25 marbles.

Ben had 50 marbles.

Charles had 35 marbles.
