**Total cost of 3 watches = rs. 2700**

**Let the cost of first watch be = RS. x**

**So, cost of second watch = Rs. 2x/3**

**Cost of third watch = 1/2 * 2x/3 = Rs. x/3**

**ATQ- x + 2x/3 + x/3 = Rs. 2700**

**→ 3x+2x+x / 3 = Rs. 2700**

**6x/3 =Rs. 2700**

**x = 2700*3/6 = 1350**

**So x = Rs. 1350**

**→ So cost of first watch = Rs. x = Rs. 1350**

**Cost of 2nd watch = 1350*2/3 = Rs. 900**

**Cost of 3rd watch = Rs. 900/2 = Rs. 450**
