Answer 1

$<b><i>Hi !$

Here is your answer !!

______________________________

C.P. of book = ₹ 200

Profit % = 20%

S.P. = ?

$\bf \: s.p. \: = \: \frac{(100 + profit \: \%)}{100} \times c.p. \\ \\ = > \bf \frac{100 + 20}{100} \times 200 \\ \\ = > \bf \: \frac{120}{100} \times 200 \\ \\ = > \bf \: 240$

S.P. = ₹ 240

Here, the S.P. is C.P. for Rohan

C.P. of the book = ₹240

Loss % = 10 %

S.P. = ?

$\bf \: s.p. \: = \frac{(100 - loss \: \%)}{100} \times c.p. \\ \\ \bf = > \bf \: \frac{100 - 10}{100} \times 240 \\ \\ = > \bf \frac{90}{100} \times 240 \\ \\ = > \bf 216$

S.P. = ₹ 216

Then , this S.P. is C.P. for Rishi

______________________________

Book sold to Rohan at =200+40=Rs240

Rohan sold book to rishi at 10%loss =240x10/100=24

Book sold to rishi at =240-24=Rs 216.

Rishi pay Rs 216 for the book
