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
