Question

Carol is given a 10% pay decrease. Her new wage is £306 per week. What would be her weekly wage if, instead, she had received a 10% pay increase?

Answer 1

the answer would be 374.00

the original value before any increase or decrease is 340.00

so...

340.00 X 1.10 = 374.00

Answer 2

New Wage after 10% increase =£374

Explanation:

Let us assume Carol's initial weekly wage be £ x

Now there is 10% decrease in weekly wage

10 % of weekly wage = 10 % of x

=
`(10x)/(100) = 0.1x`

New wage after 10% decrease = initial weekly wage - 10% of x

=
`x- 0.1x = 0.9x`

It is given that new weekly wage is £ 306

so we equate £306 and 0.9x , so we have

`0.9x=306`

`x=(306)/(0.9)` ( divide both sides by 0.9)

`x= 340`

So we got

Initial weekly wages = £ 340

Now Let us find weekly wage when there is 10% increase,

10% of initial weekly wage =
`10% of 340`

=
`(10)/(100)`×
`340`

=
`34`

New Wage after 10% increase =
`340+34`

=£ 374
