Answer 1

Given:

• Selling Price (SP) of the watch = ₹11400
• Loss% = 5%

To Find:

• Cost Price (CP) of the watch = ??

Formula Used:

$\boxed{CP = \dfrac{100}{(100-Loss\%)}\times SP}$

Solution:

$CP = Rs.\left\{\dfrac{100}{(100-Loss\%)}\times SP\right\}$

$= Rs.\left\{\dfrac{100}{(100-5\%)}\times 11400\right\}$

$= Rs.\left\{\dfrac{100}{95}\times 11400\right\}$

$= Rs.\left\{100\times120\right\}$

$= Rs.\; 12000$

Hence, the shopkeeper bought the watch for ₹12000.
