Question

the average weight of 5 persons is 61kg if each person reduces their weight by 2kg then average weight is 59kg. justify your answer​. plz ans my question please

Answer 1

Answer:

Step-by-step explanation:

Average weight of 5 people = 61kg

∴ Total weight of 5 people = 61×5=305 kg

If each person reduces their weight by 2 kg, the total weight decreases by 10 kg

∴New total wt=295 kg

Thus $Avg=\frac{295}{5}=59 kg$\

Answer 2

Step-by-step explanation:

5 people

so total weight is 5*61 = 305

if everyone reduced 2 kg

total weight reduced = 2*5 = 10

so now total weight of 5 people is 305-10= 295 kg

so average is 295/5 = 59 kg
