The price of the watch before the increase is £165.
Step-by-step explanation:
Given,
After increasing 20% price of a watch is £198
To find the price of the watch before increase.
Let,
The price of the watch is x
According to the problem,
x+x × 20% = 198
or, x+[tex]\frac{20x}{100}[/tex] = 198
or, [tex]\frac{120x}{100}[/tex] = 198
or, x = [tex]\frac{198X100}{120}[/tex]
= 165
Hence,
The price of the watch before the increase is £165.
