Question
The average weight of βxβ group members is 56 kg.
The average weight of (x β 18) women is 55 kg, of (x β 20) children is 50 kg, and of (x β 22) men is 65 kg. Find the value of x.Solution
Total weight = 56 Γ x = 56x Women = 55 Γ (x β 18) = 55x β 990 Children = 50 Γ (x β 20) = 50x β 1000 Men = 65 Γ (x β 22) = 65x β 1430 Now, 56x = 55x β 990 + 50x β 1000 + 65x β 1430 56x = 170x β 3420 170x β 56x = 3420 114x = 3420 x = 30
