Answer:
£150
Step-by-step explanation:
25% means 25 per hundred, and decreasing 200 by 25% means that we should subtract 25% of 200, from 200:
25% · 200
= [tex]\frac{25}{100}[/tex] · 200
= [tex]\frac{1}{4}[/tex] · 200
= 50
⇒ 200 - 25% · 200
= 200 - 50
= 150
Alternatively, decreasing by 25% is the same as keeping 75%
(as 100% - 25% = 75%)
75% · 200
= [tex]\frac{3}{4}[/tex] · 200
= 150
