Question

By selling 33 note bookes a shopkeeper gain the selling price of 11 notes book . Find the gain percentage.​

Answer 1

$\large\bold\orange{\underline{Answer:-}}$

$\large\implies$ (SP of 33 notebooks) - (CP of 33 notebooks) = Gain

$\large\implies$ Gain = SP of 11 notebooks

$\large\implies$ SP of 22 notebooks = CP of 33 notebooks

✯ Let CP of each notebook be ₹ 1

✯ Then,

$\large\implies$ CP of 22 notebooks = ₹ 22

$\large\implies$ SP of 22 notebooks = ₹ 33

✯ Gain $\large\implies$ ₹ (33 − 22) = ₹ 11

✯ Gain % $\large\implies$ $\large\frac{11}{22}$ × 100 = $\boxed{\bold{\purple{50 \ percent}}}$

Therefore, Gain percentage = 50%

Answer 2

Answer:

By selling 33 tables he gains the SP of 11 tables.

This means the CP of the tables will be equal to 33-11 or 22 tables.

Gain % = Profit÷ CP ×100. In terms of tables it will be 11/22 × 100 or 50%.

Now let us check if the answer fulfils the condition:

Let CP of 1 table be Rs 100 hence for 33 tables it will be Rs.3300/-

Profit is 50%. Hence SP is 150% of 3300 or Rs.4950.

Accordingly SP of 11 tables ie Rs.1650.

This is also equal to 4950-3300 = 1650.
