Answer : B
Milk left for the evening = 1 - 2/8 = 6/8
Milk consumed in the evening = 3/5 of 6/8 = 3/5 x 6/8 = 18/40
Total milk consumed = 2/8 + 18/40 = 28/40
Milk left = 1 -28/40 = 12/40 = 3/10

The mass of the big ball is 12 kg. What is the mass of the 5 balls?

A20 kg
B25 kg
C30 kg
D15 kg

What is the weight of one ball

Ans 1:

Vrushti from swami vivekanand english primary school, Mumbai

Class : Class 4

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
