Question

Со склада в первый день отпустили угля на 12т,или в 1,3 раза меньше,чем во второй,а в третий день-37,5% того,что было отпущено за первые два дня. Сколько тонн угля отпускали каждый день...

Answer 1

Х- первый день х+12 или х * 1,3 = второй день (х + (х+12) * 37,5 / 100) = третий день 1,3 х = х+12 1,3х - х = 12 0,3х = 12 х = 12 / 0,3 х = 40 в перв день тогда во второй = 52 т (40+52) *37,5 / 100 = 34,5 т в третий день

Answer 2

Давно не решал подобные штуки. y-1день, x-2, y-3

{x-12=y

{x/y=1.3

x=y+12

(y+12)/y=1.3

1+12/y=1.3

12/y=0.3

y=40

x=40+12=52

z=(x+y)*37.5=34.5

Calculating Coal Shipment

To calculate the amount of coal shipped each day, we can use the information provided.

- On the first day, 12 tons of coal were shipped, which is 1.3 times less than the amount shipped on the second day. - On the third day, 37.5% of the total amount shipped in the first two days was shipped.

Let's calculate the amount of coal shipped each day.

Step 1: Calculate the amount of coal shipped on the second day. 12 tons * 1.3 = 15.6 tons

Step 2: Calculate the total amount of coal shipped in the first two days. 12 tons + 15.6 tons = 27.6 tons

Step 3: Calculate the amount of coal shipped on the third day. 37.5% of 27.6 tons = 10.35 tons

So, the amount of coal shipped each day is as follows: - First day: 12 tons - Second day: 15.6 tons - Third day: 10.35 tons
