Question

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

Answer 1

Answer:

The cost before the increase is £250.

Step-by-step 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 :

$\frac{130}{100} \times x = 325$

Next, we have to solve it :

$x = 325 \div \frac{130}{100}$

$x = 325 \times \frac{100}{130}$

$x = 250$

Answer 2

Answer:

227.5

Step-by-step 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
