Question

Oranges are bought at $5$ for Rs.$10$ and sold at $6$ for Rs.$15$. Find profit or loss as percent.

Answer 1

We know that

LCM of $5$ and $6=30$

Consider that $30$ oranges are bought

So the C.P of $30$ oranges $=(30\times 10)/5=₹60$

S.P of 30 oranges $=(30\times 15)/6=₹75$

$Gain=S.P–C.P$

Substituting the values

$=75–60$

$=₹15$

Gain percent $=(gain\times 100)/C.P$

Substituting the values

$=(15\times 100)/60$

$=25\%$
