Answer:
Original mean =10
No.of observations=10
Let the terms be x₁,x₂,x₃......x10
mean = sum of terms/no.of terms
10 = x₁+x₂+x₃+......+x₁₀/10
10*10=x₁+x₂+x₃+......+x₁₀
100=x₁+x₂+x₃+......+x₁₀
If each term is increased by 10%,the new terms will be:
1.1x₁,1.1x₂,1.1x₃,......1.1x₁₀
New mean=Sum of terms/no.of terms
=1.1x₁+1.1x₂+1.1x₃+......+1.1x₁₀/10
=(x₁+x₂+x₃+......+x₁₀)1.1*10/10
=100*1.1=110/10=11
New mean=11
