Answer:
260%
Step-by-step explanation:
To solve how much the percentage increase cost of Jo's car insurance is, we first need to list down our variables.
1st year = £245
2nd year = £883
First off, we need to find the difference of the two.
Increase = £883 - £245
Increase = £638
Now to find the percentage increase, we take our increase and divide it by our 1st year's payment and multiply it by 100.
Percentage increase =
Percentage increase =
Percentage increase = 260%
So the percentage increase of last years payment to this years payment is 260%.
Answer:
36
Step-by-step explanation:
Here is the correct and complete question: The units digit of a two-digit number is twice the tens digit. If the digits are reversed, the new number is 9 less than twice the original number. What is the original number?
Lets assume the original number be"10y+x". (x is unit digit and y is 10th digit)
∴ if number is reversed then resulting number be "10x+y".
As given: x= 2y
and
Now, solving the equation to get original number.
Distributing 2 to 10y and x, then opening the parenthesis.
⇒
subtracting by (2x+y) on both side.
⇒
subtituting the value of "x", which is equal to 2y.
∴
⇒
subtracting both side by (16y-9)
⇒
cross multiplying
We get,
y=3
∵x= 2y
∴ x= 6
Therefore, the original number will be 36 as x is the unit number and y as tenth number.
