Given:

Arithmetic mean of 67 values = 35

Each value is multiplied by 4


To Find:

Mean of new values after multiplying each value by 4

Solution:

Let the sum of 67 values be S

Then, the arithmetic mean of 67 values = S/67 = 35

S = 67 * 35 = 2345


When each value is multiplied by 4, the new sum of values = 4S

Let the new mean be M

Then, M = (4S)/67

M = (4 * 2345)/67

M = 138.81


Therefore, the mean of new values after multiplying each value by 4 is 138.81.
