Dear Student,


Let cost price of watch for neeta=x rupeesneeta sold it to rekha at profit of 10%Hence the selling price =x+10% of x=x+10100x=1.1xNow this is the price at whch neeta bought it.she again sold it to monu at profit of 4%.Hence selling price =1.1x+4% of 1.1x=1.1x+0.04×1.1x=1.1x+0.044x=1.144xhence cost price for monu=1.54x1.144x=1430x=14301.144x=1250Hence neeta purchased the watch for 1250 rupees.
