Answer 2

★ Given ★

• C.P of 10 notebooks = Rs.40

• S.P of 1 notebook = Rs. 4.75

★ To Find ★

• Gain %

★ Solution ★

Since, S.P of 1 notebook is Rs. 4.75,

Therefore C.P of 10 notebooks = $\sf { 10 \times 4.75 = ₹47.50}$

Calculating gain-

${\boxed {\sf {Gain = S.P - C. P}}}$

${\sf{ \implies Gain = ₹47.50 - ₹40}}$

${\sf{ \implies Gain = ₹7.50 }}$

________

${\boxed {\sf {Gain% = \dfrac{Gain}{C.P} \times 100 }}}$

${\sf {\implies Gain% = \dfrac{7.50}{40} \times 100 }}$

${\sf {\implies Gain% = \dfrac{750}{40} }}$

$\sf\red {\implies Gain% =18 \dfrac{3}{4}% }$
