Question

The price of a ring was increased by 30% to £325. What was the price before the increase?

Please answer asap!!​

Answer 1

The cost before the increase is £250.

Explanation:

Given that after 30% increases, the cost of the ring is £325 so we can assume that 130% is £325. Now, we have to form an expression in term of x where x represents the original cost :

`(130)/(100) * x = 325`

Next, we have to solve it :

`x = 325 / (130)/(100)`

`x = 325 * (100)/(130)`

`x = 250`

Answer 2

227.5

Explanation:

Find the number that is increased by 30% to get to 325.

100-30 = 70.

In other words, what number is 70% of 325.

325 x .70 = 227.5

The original price of the ring was 227.5.

Check your work, 227.5 = 70% of X

227.5 / .70 = 325
