of numbers is?
a.5 b.10 c.15 d.9
​

Answer 1

Answer:

10

Step-by-step explanation:

total sum of number=6×12

total sum =72

now,

2 is subtracted from each number

then,

2×6=12

means 12 is subtracted from sum of total number

since,

72-12=60

hence the new average is

60÷6=10

since the answer is 10
