Answer / Solution

Given, cost P=5400rs

\frac{cost P}{cost Q}=\frac{3}{4}

cost Q=\frac{4}{3}\times cost P

cost Q=\frac{4}{3}\times 5400

cost Q=7200 rs


profit_q=\frac{(S.P._q-cost_q)}{cost_q}\times 100

25=\frac{(S.P._q-7200)}{7200}\times 100



Discount_q=(10000-9000) ,Discount=1000rs

%={1000 \times 100}{10000}
