Question

(111) The mean of 3, 8, 15, x and 14 is 12. Find x.​

Answer 1

Step-by-step explanation:

3 + 8 + 15 + x + 14 ÷ 5 =12

40 + x ÷ 5 =12

40 + x = 12 × 5

40 + x = 60

x= 60 - 40

x = 20

Answer 2

Answer:

20

Step-by-step explanation:

Mean=Sum of all quantities/ Total number of quantities

(3+8+15+x+14)/5 = 12

11+15+x+14=60

x+40=60

Therefore,

x=20
