Three friends divided some bullets equally. After all of them shot 4 bullets the total no.Of remaining bullets is equal to that of one has after division. Find the original number divided.
Answers
Answer:
total number of bullets at the start = 18
Step-by-step explanation:
Total number of bullets initially = 3 * x
Each of them gets X bullets after sharing.
Total number of bullets after each of them fires 4 bullets each : 3x - 3 * 4
= 3x - 12
So given 3 x - 12 = x
So 2 x = 12
x = 6
So there were totally 18 bullets in total at the beginning.
Explanation:
Let the number each had be x
.........................................................................................................
Three friends divided some bullets equally
⇒ total bullets = 3x
.........................................................................................................
They each shot 4 bullets
⇒ total bullets shot = 3 x 4 = 12
⇒ bullets remain = 3x - 12
.........................................................................................................
Remaining bullets is equal to what each had when divided:
⇒ 3x - 12 = x
⇒ 2x = 12
⇒ x = 6
.........................................................................................................
Find original number of bullets
⇒ 6 x 3 = 18
