Answer 2

7200

Explanation:

ated in survey=83 1/3% of (250/3 )/100=250/300=5X/6

Not participated=x/6

A=50%(5x/6)=2.5x/6

Un certain=0.5x/6

B=2x/6

Not in survey A=2/3 *X/6=X/9

NOT IN SURVEY B=1/3 *X/6=X/18

Un certain A = 1/5 * 0.5x/6=0.1x/6

Un certain B= 4/5*0.5x/6=0.4x/6

A= 2.5x/6 + x/9 + 0.1x/6= =7.5X+2X+0.3X/189.8X/18

B=2x/6 + x/18 + 0.4x/6= 6X+X+1.2X/188.2X/18

A-B=640

1.6X/18 =640

X=7200
