48

Step-by-step explanation:

since-30%=24kg

then 1%= 24/30

therefore 60%= 24/30×60

so, the answer is 48

Answer 2

Given: 30% of the mass of an object = 24 kg

To find: 60% of the mass

Solution:  

let the mass of the object = x kg

According to the question,

30% of x = 24 kg

On solving, (30/100) × (x) = 24

                    x = (24 × 100)/30

                    x = 80 kg

Hence, mass of the object= 80 kg

So, 60% of 80 = (60/100) × 80

                        = 48 kg

Hence, 60% of the mass of the object = 48 kg
