Answer 1

Step-by-step explanation:

40/1.15=34.78 {C.P}

so 34.78 X1.2=41.74 is the answer

Answer 2

He should have sold it for Rs. 41.74.

Step-by-step explanation:

Since we have given that

Selling price of a book = Rs. 40

Profit % = 15%

So, Cost price of a book would be

$\dfrac{100}{100+15}\times 40\\\\=\dfrac{100}{115}\times 40\\\\=Rs.\ 34.78$

if profit% = 20%

So, Selling price would be

$\dfrac{100+20}{100}\times 34.78\\\\=\dfrac{120}{100}\times 34.78\\\\=41.74$

Hence, he should have sold it for Rs. 41.74.
