Answer:
7 kg
Step-by-step explanation:
Let the Mass of the circle shaped figure be m kg and triangle shaped figure be n kg.
Therefore, from the first figure
2m + 3n = 32 ---(i)
and from the second figure,
2m + n = 20 ----(ii)
Multiplying eqn (ii) by 3,
6m + 3n = 60 ---(iii)
Subtract (i) and (iii),
2m + 3n - 6m -3n = 32 - 60
=> -4m = -28
=> m = 28/4
=> m = 7
Therefore, mass of the circle shaped figure is 7 kg.

Answer: 7kg
let the weight of triangular piece be x and spherical be y
so,
in first
3x+2y=32
or,2y=32-3x............(1)
in second
x+2y=20
or,2y=20-x..........(2)
from 1 and 2
32-3x=20-x
12=2x
x=6
putting value of xin (1)
2y=32-3*6
2y=14
y=7
in third
weight of 1 spherical piece =7kg
