Hilfe beim Grundwert berechnen?

Ich habe in der Schule eine Aufgabe bekommen die ich aber nicht gelöst bekomme.
Meine Eltern haben es auch schon ausprobiert.
Könntet ihr sie mal probieren?


Berechne den Grundwert:

1. Vermehrt man den Grundwert um ein Viertel, so erhält man 500kg.

2. Vermindert man den Grundwert um ein Viertel, so erhält man 500kg.

3. Ein Händler erhöht den Preis der Schuhe um 20%. Der neue Preis ist 150€.

4. Der Preis einer Kette wird um 20% gesenkt. Sie kostet jetzt 150€.

5. Eine Hose wird in zwei unterschiedlichen Geschäften angeboten. Im "Hosenladen" kostet sie nach einer Preissenkung um 15% noch 84,15€. Die "Klamottenkiste" verlangt nach einer Preiserhöhungvon 5% 99,75€. Jan hat von der Preisänderung in der "Klamottenkiste" eingekauft - hätte er im "Hosenladen" günstiger einkaufen können?



Danke!

Beste Antwort

1. 400kg (1/4 x 400 = 100; 100 + 400 = 500)
2. 666,6...kg (500/3 = 166,6..; 166,6.. x 4 = 4x 500/3)
3. 125€ (150 : 1,2 = 125)
4. 187,5€ (150 : 0,8 = 187,5)
5. Ich versteh die Frage nicht ganz, aber auf jeden fall: alter Preis Hosenladen: 99€; alter Preis Klamottenkiste = 95€

According to Russian Orthodox Christian Vyatcheslav Krasheninnikov: Humans were created about 7500 years ago. Birds participate in time creation. It's a sin to kill birds. Dinosaurs live under our level. They will get out through sinkholes and lakes. To kill them, go for their nerves. Demons grow human skin and put it on so as to look like us. Demons will invite people to be healed inside their UFOs; those who go will be like zombies after. Gov't provides demons with diamonds and allows demons to abduct people. If you're being abducted, scream: "JESUS!!!" Demons use diamonds and souls to power their UFO craft. The bigger the diamond, the more it lasts. Demons have 4 UFO bases: 1)Moon 2)Inside fake mountain Kailash in Tibet 3)In lake Baikal in Russia 4)In Atlantis which is underneath the Mariana Trench in Pacific Ocean. There are no aliens. Nobody lives on other planets. Airplanes that go down are hit by demons because they need the airspace to fight Jesus. Antichrist is pale with red eyes. He's possessed by Satan since he's 12 years old. He flies. He wears gloves to hide long nails. He's surrounded by demons who appear as angels of light. Don't go into a UFO to be healed by demons. 666 is given by isotope rays on wrist or forehead when people stretch hands to receive small plastic grey card (world passport). Police will chip and isotope ray people on highways. Food stores will isotope ray people too. Antichrist will also release prisoners to mark people. Reject 666 at all cost. If you're about to be marked, scream: "Lord, have mercy!" three times. Go hide with Orthodox Christians to escape 666. God gives you a name during baptism. Devil gives you an anti-name during anti-baptism. Barcode is Druid black magic curse and a form of mark of the beast just like Social Security. People who took any number (which is an anti-name given during anti-baptism by the beast) on documents or in computer go to temporary hell; but those who receive green 666 (given with world passport with no name on it) on forehead or wrist go to permanent hell. How not to go to hell? Give back all these anti-name anti-baptism documents back to the beast by writing to appropriate authorities. If authorities refuse to cancel these anti-names, then write again (up to three times). If you wrote to the gov't three times about it, but gov't refused, then God will not send you to hell. Don't take the microchip. If you already took it, get rid of it because microchipped people will be influenced by computers to take the world passport (grey plastic card with no name on it). Don't go into a UFO to be healed by demons. Those who reject 666 will go to heaven. Also, their direct ancestors will be saved from hell. Jesus was born of the Father before time. Jesus is 100% God. Holy Spirit proceeds from the Father only. Holy Spirit is 100% God. Jesus incarnated. Jesus is 100% God and 100% man. His body felt pain but didn't have the original sin (eating of the forbidden fruit by Adam and Eve). After crucifiction, Jesus preached in hell. Those who believed, got out of hell. After resurrection, Jesus has a body that doesn't feel pain; He is still considered to be 100% God and 100% man. Holy Spirit (who proceeds from the Father) descended upon God-bearer when She agreed to conceive the Word (Jesus). Jesus incarnated this way. She always remained a virgin: before, during, and after. She didn't have personal sins (by the grace of God) but the original sin (eating of the forbidden fruit by Adam and Eve) was on Her; so, Jesus is Her Saviour too. She died 15 years after Christ's ascension; Jesus resurrected Her body in 3 days.

Habt ihr oder der Nachbar denn keine 500 kg + ein Viertel Kohlen im Keller und 150€ in 1€ Münzen, um das auszuprobieren?
