Step-by-step explanation:
mean of 10 nuumbers = 20
then multiply the mean by total numbers = 10×20
=200
also, multiply the number by which we have to subtract the mean = 5×10 = 50
subtract total number from 50 = 200-50= 150
then divide the number obtained by subtracting by ten to get the mean = 150/10 =15
