When the sum of 21 and 4 is doubled so it comes to 50.

Given that,

  • There are two numbers i.e. 21 and 4.
  • Now the sum of these two numbers is = 21 + 4 = 25

After the sum or adding of these numbers, we have to double it i.e.

= (25) (2)

= 50.

Therefore we can conclude that when the sum of 21 and 4 is doubled so it comes to 50.
