Answer 1

Oranges are bought at $5$ for $Rs.10$

Cost of $5$ oranges is $Rs.10$

So,cost of one orange $=\frac{10}{5}=Rs.2$

So the cost of $6$ oranges$=2\times 6=Rs.12$

Cost of $6$ oranges is $Rs.12$

Cost price$=c.p=12$

Selling Price$=s.p=15$

so profit $=s.p-c.p=15-12=Rs.3$

profit $\%=\frac{profit\times 100}{C.P}=\frac{3\times 100}{12}=25\%$

$\therefore$the profit $\%$ is $25\%$
