Question

hi everyone..i have 2 hard math questions and i really want help..i would be thankful for u if u try to help me solving themm..thnx
q1:If an employer reduces the working week from 40 hours to 35 hours, with no loss in weekly pay, calculate the percentage increase in the hourly rate of pay?
q2: Given that G=AB, find the percentage increase in G when both A and B increase by 10%

plz show ur work..

Answer 1

Question 1:

Originally:
Let him be paying x bucks for 40 hours.
Thus, for one hour, he pays x/40 bucks....
Now:
he is paying x bucks for 35 hours.
Thus, for one hour, he pays x/35 bucks....
Percentage increase= {(Final-Original)/Original} * 100=
= (100/7)=14.28%

Question 2:

G=AB
A now becomes 110A/100 and B becomes 110B/100
thus, G= 1.21AB
Percentage increase= (1.21-1.00)*100=21%

I really hope that helped you; anyways, you just copy what I have written there, your teacher will be happy enough!! lol!

Answer 2

Call x=hourly rate of pay.
The weekly pay= x( the hourly rate) times the number of hours worked.
For the 40 hr week, the weekly pay w=40x
For the 35 hr week, call the hourly rate y.
Then w=35y
35y=40x
y/x=40/35=8/7=1 1/7=1.142587
so the increase in hourly rate was about 14.3%

2) G=AB If A and B each increase by 10%, then
G=(1.1A)(1.1B)=1.21AB so G increased by .21 or 21%

Answer 3

Suppose hourly rate is x. You get 40x for a week. When the working hours are reduced to 35 , you earn 40x for 35 hrs , ie 40x/35=8x/7 per hr. The increase is (8/7-1)x=x/7 over x.Incr is thus 100/7 per cent

2) G=AB. By 10 % increase A becomes A+A/10, etc

New G = ( A+A/10)(B+B/10)
=AB(11/10)(11/10)
=AB(121/100)
New G-Old G=AB(21/100)

Incr is 21%

Answer 4

Q1)
You are paying same amount of pay for 40hrs and 35 hrs.
So let us consider change in hourly rate at 35hr/week is x%
Then 35 * x = 40
therefore x = 40/35 = 1.14
Here in 1.285, 1 is 35 and 0.285 is additional change
So the percentage change will be 14% per hour.


Q2) The percentage increase in G will be 21%
This answer I found using excel I tried intrepreting this answer but could not prove it.

Answer 5

q1) the rate will be increased by (40/35) = 1.14 %

q2) G = AB
(x)(G) = (1.1)(A)(1.1)(B)
(x)(G) = (1.21)(A)(B)
x = 1.21
percent increase is 21%
