​

Answer 1

Answer:

Let the number be x.

Then, according to given condition, we have

x - 21 = 71 - x

i.e. x + x = 71 + 21

i.e. 2x = 92

begin mathsize 12px style straight i. straight e. straight x equals 92 over 2 straight i. straight e. straight x equals 46 end style

Thus, we have

46 - 21 = 25 and 71 - 46 = 25

Hence, the number is 46.
