Question

Two fifths of a number is subtracted from half of the number. If the result is 4, what is the number?

Answer 1

Answer:

-40

Step-by-step explanation:

2/5X - 1/2X = 4

then by simplifying the denominator we get

-X/10=4/1

= -X=40

X= -40

Answer 2

Answer:

Let the number be x.

Therefore,

From given condition,

x/2-2x/5=4

→5x-4x/10=4

→x/10=4

→x=10×4

→x=40

Therefore the number is 40.
