Given

  • The difference between two numbers is 23.

  • The larger number is x.

(I) Hence, The smaller number would be x - 23 so that the difference between two numbers become 23.

(ii) If the sum of two numbers is 91, then

x + x - 23 = 91

=> 2x - 23 = 91

=> 2x = 91 + 23

=> 2x = 114

=> x = 57

Thus, the larger number = x = 57.

And the smaller number = x - 23 = 57 - 23 = 34.

Hence, the two number is 34 and 57 respectively.

Answer:

  • Difference b/w two numbers = 23
  • Larger number = x

(i) The expression for smaller number.

⇒ Difference b/w two numbers = 23

⇒ Larger number - Smaller number = 23

⇒ x - Smaller number = 23

⇒ x - 23 = Smaller number

Smaller number = x - 23

⠀⠀⠀⠀⠀───────────────

(ii) The smaller number, if the sum of these two numbers is 91.

⇢ Sum of both numbers = 91

⇢ Larger number + Smaller number = 91

⇢ x + x - 23 = 91

⇢ 2x = 91 + 23

⇢ 2x = 114

  • Dividing both by 2

⇢ x = 57

◗ Smaller number = x - 23 = (57 - 23) = 34
