Given data -
5, 10, 15, 20, 25, 6, p, 6, 10, 5
mean =15
∴, (5+10+15+20+25+6+p+6+10+5)/10=15
or, (102+p)/10=15
or, 102+p=15×10
or, 102+p=150
or, p=150-102
or, p=48
∴, the required value is: p=48
5, 10, 15, 20, 25, 6, p, 6, 10, 5
mean =15
∴, (5+10+15+20+25+6+p+6+10+5)/10=15
or, (102+p)/10=15
or, 102+p=15×10
or, 102+p=150
or, p=150-102
or, p=48
∴, the required value is: p=48
