Answer:

Step-by-step explanation:

Let the price before the increase  = £ x

(100+20)% of x = £156

120% of x = 156

[tex]\frac{120}{100}*x=156\\\\x=156*\frac{100}{120}\\[/tex]

x = £ 130

Before the increase it was 100%
So 20+100=120
156/120*100=130$

Don’t do it like 20/100 *156 and then minus it from 156 because you will get a wrong answer
