Given weights are A= 60 kg, B= 45 kg, C= 54 kg,

We know the formula,

 $\mathrm{Average} \left(\mathrm{A}\right)=\frac{\mathrm{Sum} \mathrm{of} \mathrm{given} \mathrm{values} \left(\mathrm{S}\right)}{\mathrm{Total} \mathrm{number} \mathrm{of} \mathrm{values} \left(\mathrm{N}\right)}$

 Here,

 Sum of given weights (S)

= 60+45+54

= 159

Total number of persons (N)= 3

Substituting these values we get (A),

 $= \frac{159}{3}=53$

Hence, Option A is correct.
