left side weight is 12 + 6(small ball) = 6 + 6 + 6 ( which means 12 + 6 + 6 + 6 + 6 = 36)

Ans 2:

Class : Class 10
Answer: C (36 kg)
The option C should be 36 kg and not 30 kg. Corrected the mistake.

Solution:
Let the weight of the small ball be x.
3x = 12 + x
2x = 12
x = 6
Weight of 5 balls = 12 + 6+ 6+ 6 +6 = 36kg

Ans 3:

Class : Class 5

Ans 4:

Class : Class 3
I think they are asking for the mass of all 5 balls together. The mass of small ball is 6 Kg. Hence the total mass = 12 + 6 + 6 + 6 + 6 = 36.

Ans 5:

Class : Class 10
Answer: C (36 kg)
The option C should be 36 kg and not 30 kg. Corrected the mistake.

Solution:
Let the weight of the small ball be x.
3x = 12 + x
2x = 12
x = 6
Weight of 5 balls = 12 + 6+ 6+ 6 +6 = 36kg
