Answer 2

Answer:

a. 12.5

Step-by-step explanation:

$sp1 = rps144 \\ loss = 1 \div 7 \times cp \\ loss = 1 \div 7 \times cp = c - 144 \\ = 6 \div 7 \times cp = 144 \\ \\ = cp = 168 sp = 189 \\ gain\% = sp - cp \div cp \times 100\% \\ 189 - 168 \div 168 \times 100\% \\ 21 \div 168 \times 100 \\ 1 \div 8 \times 100 \\ 12.5\%$
