Question eight. On A Sunny Morning, A Greengrocer Places 200 Kilograms Of Cucumbers In Cases In Front Of His Shop. At That Moment, The Cucumbers Are ninety nine% Water. In The Afternoon, It Turns Out That It Is The Hottest Day Of The Year, And As A Result, The Cucumbers Dry Out A Little Bit. At The End Of The Day, The Greengrocer Has Not Sold A Single Cucumber, And The Cucumbers Are Only ninety eight% Water. How Many Kilograms Of Cucumbers Has The Greengrocer Left At The End Of The Day?

Answer :

Answer 1:

In the morning, the 200 kilograms of cucumbers are ninety nine% water. So the non-water part of the cucumbers has a mass of two kilograms. At the cease of the day, the cucumbers are 98% water. The last 2% remains the two kilograms of non-water fabric (which does now not change whilst the water evaporates). If 2% equals 2 kilograms, then one hundred% equals a hundred kilograms. So, the greengrocer has one hundred kilograms of cucumbers left at the end of the day..

She Leaves Some Of These Standard Boxes Empty, And In All The Other Standard Boxes She Puts 8 (empty) Small Boxes. Now, 102 Of All The Boxes On The Table Are Empty. How Many Boxes Has Barbara Used In Total?

Answer :

By putting 8 containers in a container, the full quantity of empty packing containers increases with the aid of eight - 1 = 7. If we call x the wide variety of times that 8 containers have been installed a container, we realize that eleven + 7x = 102. It follows that x=thirteen. In general, 11 + thirteen × 8 = one hundred fifteen packing containers had been used.

Question sixteen. A Swimmer Jumps From A Bridge Over A Canal And Swims 1 Kilometer Stream Up. After That First Kilometer, He Passes A Floating Cork. He Continues Swimming For Half An Hour And Then Turns Around And Swims Back To The Bridge. The Swimmer And The Cork Arrive At The Bridge At The Same Time. The Swimmer Has Been Swimming With Constant Speed. How Fast Does The Water In The Canal Flow?

Answer :

If you've got written down a full paper of mathematical formulation, you've got been wondering too complicated...It is plain that the cork does not flow extraordinarily to the water (i.E. Has the equal velocity because the water). So if the swimmer is swimming faraway from the cork for 1/2 an hour (up circulate), it'll take him every other 1/2 hour to swim returned to the cork again. Because the swimmer is swimming with constant speed (constant particularly to the rate of the water!) you may have a look at it as though the water in the river doesn't circulate, the cork doesn't flow, and the swimmer swims a certain time far from the cork and then back. So in that one hour time, the cork has floated from 1 kilometer up movement to the bridge. Conclusion: The water in the canal flows at a speed of 1 km/h..

 

Question 17. Tom Has Three Boxes With Fruits In His Barn: One Box With Apples, One Box With Pears, And One Box With Both Apples And Pears. The Boxes Have Labels That Describe The Contents, But None Of These Labels Is On The Right Box. How Can Tom, By Taking Only One Piece Of Fruit From One Box, Determine What Each Of The Boxes Contains?

Answer :

Tom takes a bit of fruit from the field with the labels 'Apples and Pears'. If it's far an apple, then the label 'Apples' belong to this box. The container that said 'Apples', then of course should not be categorised 'Apples and Pears', because that would imply that the box with 'Pears' might were categorized successfully, and that is contradictory to the truth that none of the labels changed into correct. On the container with the label 'Appels' have to be the label 'Pears'. If Tom could have taken a pear, the reasoning might were in a comparable way. .

Question 20. On A Sunny Morning, A Greengrocer Places 2 hundred Kilograms Of Cucumbers In Cases In Front Of His Shop. At That Moment, The Cucumbers Are 99% Water. In The Afternoon, It Turns Out That It Is The Hottest Day Of The Year, And As A Result, The Cucumbers Dry Out A Little Bit. At The End Of The Day, The Greengrocer Has Not Sold A Single Cucumber, And The Cucumbers Are Only 98% Water. How Many Kilograms Of Cucumbers Has The Greengrocer Left At The End Of The Day?

Answer :

In the morning, the 2 hundred kilograms of cucumbers are 99% water. So the non-water part of the cucumbers has a mass of 2 kilograms. At the end of the day, the cucumbers are 98% water. The remaining 2% remains the two kilograms of non-water cloth (which does not trade while the water evaporates). If 2% equals 2 kilograms, then 100% equals 100 kilograms. So, the greengrocer has a hundred kilograms of cucumbers left on the end of the day. 

Question 21. A Boy Leaves Home In The Morning To Go To School. At The Moment He Leaves The House He Looks At The Clock In The Mirror.

Question 34. You Walk Upwards On An Escalator, With A Speed Of 1 Step Per Second. After 50 Steps You Are At The End. You Turn Around And Run Downwards With A Speed Of 5 Steps Per Second. After 125 Steps You Are Back At The Beginning Of The Escalator. How Many Steps Do You Need If The Escalator Stands Still?

Answer :

Let v be the speed of the escalator, in steps in line with second. Let L be the variety of steps which you want to take whilst the escalator stands nevertheless. Upwards (together with the escalator), you stroll 1 step in step with second. You want 50 steps, in order that takes 50 seconds. This gives: L - 50 × v = 50. Downwards (towards the course of the escalator), you walk five steps according to 2d. You want one hundred twenty five steps, in order that takes 25 seconds. This gives: L + 25 × v = a hundred twenty five. From the two equations follows: L = a hundred, v = 1. When the escalator stands still, you want a hundred steps.
