In a store, a certain garment is marked at a price of 40% higher than the cost price, and then sold at a 20% discount. As a result, the price of each garment is 140 yuan. How much is the cost price of the garment?

Let the cost price of the garment be X
(1+40%x)80%=15
x=140(1.4x0.8)
x=125

A store will increase the price of a certain garment by 40% and then sell it at a discount of 20% (80% of the price). As a result, each garment can still make a profit of 15 yuan. Then the cost of each garment is ()
A. 120 yuan B. 125 yuan C. 135 yuan D. 140 yuan

Suppose the cost of each piece of this kind of clothing is x yuan. According to the equation, we get x + 15 = (x + 40% x) × 80%. Solving this equation, we get x = 125, then the cost of each piece of this kind of clothing is 125 yuan

A store will increase the price of a certain garment by 40% and then sell it at a discount of 20% (80% of the price). As a result, each garment can still make a profit of 15 yuan. Then the cost of each garment is ()
A. 120 yuan B. 125 yuan C. 135 yuan D. 140 yuan

A bundle of sugarcane 150 yuan, a total of 17, cut into two shapes of size, big five yuan, small three yuan! Find the size of the number of roots, when the biggest profit!

The profit is the most, that is to say, you can get the most money. OK, let's set the big x root and the small y root. Then the equation is as follows:
X + y = 17, profit = 5x + 3Y, let the profit value be Z, that is, there is Z = 5x + 3Y, when 5x = 3Y, the profit is the largest, the solution is simple
Y=10,X=7

A clock, it is 12 o'clock, type a word!
(people's education press Chinese Grade 5 Volume 1 unit 5 riddles of Chinese characters)

Because the riddle is a clock, which refers to twelve o'clock, isn't "ten" plus two o'clock "the word" dou "?

Guess the puzzle. On the dial of a clock, the hands coincide at 12 o'clock?

On the dial of a clock, the hands coincide at 12 o'clock?
The answer to the riddle
[explanation] Dou, the word is: Ten + two points

Look at the picture and guess the puzzle. A clock pointer points to 12 o'clock

It should be a "country"
Mouth shaped clock (frame)
Jade is broken, is twelve
Together, it's a national character

A clock is 3 minutes slow per hour. According to this calculation, when the clock points to 12 o'clock in the evening after 5 o'clock in the morning, what is the standard time?
60-3 = 57 (minutes) 24-5 = 19 (hours) 19:00 = 1140 minutes 1140 △ 57 = 20 (hours) 20 + 5 = 25 (hours) = 1:00 a.m
Is this wrong? What's wrong? Is this right,

You should find this clock. It takes 60 / 57 minutes to go one square
After 5:00 in the morning, when the clock points to 12:00 in the evening, the number of squares of the clock is (24-5) * 60 = 19 * 60 = 1140
The time used is: 1140 * 60 / 57 = 1200 minutes = 20 hours
5 + 20 = 25 = 1 am

A clock every hour slow 3 minutes, according to this calculation, 5:00 in the morning after the alignment time, when the clock points to 12:00 in the evening, what is the standard time
A clock slows down 3 minutes per hour. According to this calculation, when the clock points to 12 o'clock in the evening after 5 o'clock in the morning, the standard time is what time and what minutes must be answered by senior mathematics teachers. We have been arguing with teachers for a long time! Please be original! This question concerns whether I can continue to go to school!

One clock is three minutes slow per hour,
So the actual time is one hour, and this clock only goes: 60-3 = 57 minutes
From 5:00 a.m. to 12:00 p.m., 19 hours = 1140 minutes
Actual time: 1140 △ 57 × 60 = 1200 minutes = 20 hours
It's actually one o'clock the next day

A clock is three minutes slow per hour. According to this calculation, after 5:00 in the morning is aligned with the standard time, when the clock points to 12:00 in the evening, the standard time is Time Points

12 + 12 = 24, the standard time has passed x hours, and (5 + x-24) × 60-3x = 0, (5 + x-24) × 60-3x (5 + x-24) is (5 + x-24) × 60-3x = 0, and (5 + x-24) × 60-3x = 0, and (5 + x-24) is (5 + x-24) is (5 + x-24) × 60-3x = 0, (5 + x-24 (5 + x-24) × 60 (X-19 (x-19-19) - 3x = 0, and & amp & nbsp; & & nbsp; & & nbsp; & amp & amp & amp & nbsp; & & nbsp; & & amp & nbsp; & & nbsp; & & nbsp; & nbsp; & & nbsp; & & nbsp; & & nbsp; & nbsp; & nbsp; & & nbsp; & nbsp; & & nbsp; & & nbsp; & & nbsp; & & amp & nbsp; & & nbsp; & nbsp; & nbsp; & nbsp; & & nbsp; & nbsp; & & nbsp; & nbsp; & nbsp; & & nbsp; & nbsp; & nbsp; & nbsp; & & nbsp; & nbsp; X = 20; 5:00 + 20 = 25:00, 25:00-24 = 1:00; so the standard time is 1:00
