Answer 1

Answer:

x=24

y=36

z=72

Step-by-step explanation:

Given,

three boys X, y, and Z share 132 copies of computer games.

X+Y+Z=132

the ratio is X's share to Y"s is 2:3. the ratio of Y's to Z's is 1:2.

X:Y=2:3

Y:Z=1:2

X     :      Y

              Y       :       Z

---------------------------------

2     :       3

              1         :       2

--------------------------------

2*1   :     3*1      :      3*2

---------------------------------

2     :     3        :       6

let A:B:C=2x:3x:6x

A+B+C=2x+3x+6x

A+B+C=11x

11x=132

x=12

X'share is 2x

2*12=24

Y's share is 3x

3*12=36

Z's share is 6x

6*12=72
