Question

If the mean of 10 number is 35 and each number is increased by 2 find mean of new set of numbers

Answer 1

Answer:

37

Step-by-step explanation:

mean × no. of observations = sum

10 × 35 = 350

Now if each of the observation is is increased by 2 then,

new sum = 350 + 2 × 10

= 350 + 20

= 370

new mean = new sum÷ no. of observations

= 370 ÷ 10

= 37
