Question

Ах сложно, помогите ))))***Заработные платы рабочего за январь и февраль относятся как 9:8, а за февраль и март как 6:8. За март он получил на 450 руб больше, чем за январь, и за перевыполнение квартального плана рабочему начислили премию в размере 20% его трёхмесячного заработка. Найдите размер премии.

Answer 1

A1/A2=9/8; A2/A3=6/8; A1=(9/8)*A2; A3=(8/6)*A2; A3-A1=450; (8/6)A2-(9/8)*A2=450; (5/24)*A2=450; A2=(24*450)/5=2160; A1=(9/8)*2160=2430; A3=(8/6)*2160=2880; P=(2160+2430+2880)*0,2=7470*0,2=1494.

Answer 2

Calculation of Bonus

To calculate the bonus, we need to determine the worker's earnings for each month and the amount of the bonus based on the quarterly plan. Let's break down the given information step by step:

1. The ratio of the worker's earnings for January and February is 9:8. 2. The ratio of the worker's earnings for February and March is 6:8. 3. The worker received 450 rubles more for March than for January. 4. The bonus is 20% of the worker's three-month earnings.

Let's calculate the worker's earnings for each month:

1. Let's assume the worker's earnings for January are x rubles. 2. According to the given ratio of 9:8, the worker's earnings for February would be (8/9) * x rubles. 3. According to the given ratio of 6:8, the worker's earnings for March would be (8/6) * (8/9) * x rubles.

Now, let's set up an equation using the information that the worker received 450 rubles more for March than for January:

(8/6) * (8/9) * x - x = 450

Simplifying the equation:

(64/54) * x - x = 450 (10/54) * x = 450 x = (450 * 54) / 10 x = 2430 rubles

Now that we have the worker's earnings for January (x = 2430 rubles), we can calculate the earnings for February and March:

- Earnings for February: (8/9) * 2430 = 2160 rubles - Earnings for March: (8/6) * (8/9) * 2430 = 2560 rubles

Next, let's calculate the bonus based on the worker's three-month earnings:

Total earnings for three months: 2430 + 2160 + 2560 = 7150 rubles

The bonus is 20% of the three-month earnings:

Bonus = (20/100) * 7150 = 1430 rubles

Therefore, the size of the bonus is 1430 rubles.

Please note that the calculations are based on the given information and assumptions made.
