Question

If 1/2 is subtracted from a number and the difference is multiplied by 4, the result is 5. What is the

number ?

(A) 8/9 (B) 7/4 (C) 6/4 (D) 1/3​

Answer 1

Answer:

Let the number be x

½ is subtracted from x which will give x – ½

And the difference is multiplied with 4 [x – 1/2] × 4 to give 5

[x – 1/2] × 4 = 5

4x – ½×4 = 5

4x -2 = 5

4x = 5 + 2

x = 7/4

Answer 2

Answer:

7/4

Step-by-step explanation:

Let the required number be X

4(x-1/2) =5

4x-2=5

4x=7

x=7/4
