Question

By selling 33 books, a shop-keeper gains the selling price of
11 books. His gain percent is:
(b) 30%
(c) 40%
(d) 50%
(a) 20%​

Answer 1

Answer:

Step-by-step explanation:

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.
