The answer you are looking for is B. 22 R7.
To find this you simply divide 469 by 21. You can find this by doing long division.
Here's an image to show how I used long division to find the answer. To check the answer simply multiple the divisor (21) by the quotent (22) then add the remainder (7). Thus making the answer B.
I hope this helps!

Answer is : Price before increase is £250
Explaination:
Let the Original price of a ring = x
Increase price( g) = 30%
New price(n) = £325
x = ( 100*n)/ (100+g)
x= (100*325)/(100+30)
x= (200*325)/130
x= 250
Therefore price before increase is £250
Another method:
Given that after 30% increases,
the cost of the ring is £325 so we can assume that 130% (100+30) is £325.
Now, we have to form an expression in term of x where x represents the original cost :
130/100*x=325
Solving x
x= 250
So the original price or price before the increase is £250
Two geometry theorems get a workout here:
1) The sum of the angles of any triangle is 180 degrees,
2) If two angles are supplementary, their sum is 180 degrees.
From this we know that ∠RST + ∠STR + ∠TRS = 180. in ΔRST.
Next, look at line QS with points Q, R, and S. A straight line measures 180 degrees. and any two angles created by the line are supplements.
So, ∠QRT + ∠TRS = 180
Since we have two things equal to 180, we can set them equal to one another through transitivity (if a = b and b = c, then a = c).
∠RST + ∠STR + ∠TRS = ∠QRT + ∠TRS
Now we put in values we know for x.
(9 + x) + 5x + ∠TRS = 9x + ∠TRS
∠TRS was not filled in, but that's okay. If we subtract it from both sides, it won't be there regardless of its measure. The rest of this problem plays out like algebra class.
9 + x + 5x = 9x
9 + 6x = 9x
9 = 3x
x = 3
So x = 3, and we can find our angle measures for all angles in the problem.
