Question

The sum of the weight of a and c is equal to 220 kg, the weight of b is equal to three times they weight of c, the total weight of b and c is 92kg, where c weight is 23kg, what will be the weight of a,b and c altogether

Answer 1

a+c=220

b= 3*c (1)

b+c=92

substituting b with 1

3*c + c =92

4*c =92

c=92/4

c=23

given a+c=220

a+23=220

a=197

b=3*23

b=69

so a+b+c=197+69+23=289
