The retailer sold each watch for Rs 666
Let's denote the cost price (CP) of each watch as
.
The retailer bought 6 watches for Rs 3,330, so the total cost is given by:
![\[6x = 3,330\]](https://img.qammunity.org/2024/formulas/mathematics/college/modf627x4jskjl2gznqwudklwhgazwon40.png)
Now, we can find the cost of each watch
:
![\[x = (3,330)/(6)\]](https://img.qammunity.org/2024/formulas/mathematics/college/xupk3z7qie7uywbb6uz3fdvjp2zzbhq30q.png)
![\[x = 555\]](https://img.qammunity.org/2024/formulas/mathematics/college/rb1os4wkd8ekl8c274km7vclc0a3ahurax.png)
Now, the retailer sold each watch at a gain of Rs 111, so the selling price (SP) of each watch is:
![\[SP = CP + \text{Gain}\]](https://img.qammunity.org/2024/formulas/mathematics/college/nqx258qv2497k7tm57i1dot0wuqf2vun2s.png)
![\[SP = 555 + 111\]](https://img.qammunity.org/2024/formulas/mathematics/college/dvjj4glqgtkldi2vxqejwug4cnk00bedza.png)
![\[SP = 666\]](https://img.qammunity.org/2024/formulas/mathematics/college/gi5mla5lmvo6dkm6ycw54l2uoeuh86qc6v.png)
Therefore, the retailer sold each watch for Rs 666.
The probable question may be: "A retailer bought 6 watches for Rs 3,330 and sold them at a gain of Rs 111 from each watch. At What Price Did He Sell Each Watch?"
