Answer:
C.P. of 200 textbooks = 12000 rupees.
Profit = C.P. of 20 textbooks
Therefore, S.P. of 200 textbooks
= C.P. of 200 textbooks + C.P of 20 textbooks
= C.P. of 220 textbooks.
C.P. of 1 textbooks = 12000/200 = 60 rupees.
Therefore, S.P. of 200 textbooks
= 220 × 60
= 13200 rupees
Therefore, profit per cent
= {(13200 – 12000) ÷ 12000} × 100
= {1200/12000} × 100
= 10%
