Answer 2

Dear Student,

◆ Answer -

6 is the other number.

● Explanation -

Let x be the required no.

Given that mean of two number is 13.

Mean = sum of numbers / 2

13 = (20 + x) / 2

13 × 2 = 20 + x

26 = 20 + x

x = 26 - 20

x = 6

Hence, the other number is 6.

Thanks dear. Hope this is helpful to you...
