Question

A person got20% profit by selling 20 items in 60 rupees . how many items did he buy in 60 rupees

Answer 1

Selling Price of 20 items = Rs. 60

S.P. of 1 item = 60/20 = Rs. 3

Profit% = 20%

Then, Cost Price of 1 item :

$3 \times \frac{100}{120} \\ \\ = > \frac{30}{12} = 2.5$



So, the Cost Price of 1 item = Rs. 2.5

Then, items that he bought in Rs. 60 :

$\frac{60}{2.5} \\ \\ = > \frac{600}{25} = 24$

So, he bought 24 items in Rs. 60
