Cost reduction

Windbreaker cost after discounted SKK 1275, which were 3/4 of original price. How many SKK originally cost windbreaker? How many SKK was cost reduction?

Result

x =  1700 Sk
y =  425 Sk

Solution:

a=1275 x=a 4/3=1275 4/3=1700 Ska=1275 \ \\ x=a \cdot \ 4/3=1275 \cdot \ 4/3=1700 \ \text{Sk}
y=xa=17001275=425 Sky=x-a=1700-1275=425 \ \text{Sk}
