Question

Find different sets of 6 different numbers between 10 and 30 with each number given below as mean:

i. 20 

ii. 15 

iii. 25

Answer 1

i. The mean of 6 numbers is 20.

ie; sum = 6 x 20 = 120 (Write 3 pairs with sum 40)

i.e., 15, 25, 18, 22, 19, 21

ii. The mean of 6 numbers is 15 i.e; sum = 6 x 15 = 90

(Write 30 pairs with sum 3)

12, 18, 13, 17, 14, 16

iii. Mean is 25

sum = 25 x 6 = 150

(Write 50 pairs with sum 3)

22, 28, 23, 27, 24, 26
