Answer / jjb

a+b+c = 100
b = c
a.95 + b.100 + c.70 = (a+b+c).90

in this system of 3 linear equations with 3 unknown values, replace c by b , since they are equal:

a = 100 -2.b
a.95 + b.170 = 9000

then:

9500 + b.(170 - 190) = 9000

or:

500 = 20.b

The correct answer is b = c = 25 kg, a = 50 kg.
