Answer 1

$\pink{\huge{\underline{\star Solution\star}}}$

Let the cost price of watch = ₹ x

$Profit = \frac{1}{6}$

Selling Price = ₹ 1505

$\pink{\underline{Formulae}}$

Profit = Selling Price - Cost Price

$Profit + Cost\: Price = Selling \:Price \\\implies \frac{x}{6} + x = 1505 \\\implies \frac{x+6x}{6} = 1505 \\\implies 7x = 1505 \times 6 \\\implies x= \frac{1505\times 6}{7}\\\implies x = 1290$

$\red{\underline{Answer}}$

$\pink{\boxed{ Cost\:Price= Rs\: 1290}}$

7x=9030

x = 9030/7

x = 1290 rupees

So,the cost price of watch is ru. 1290.
