Answer:
Cost of Fan is 450
Cost of Watch is 3150
Step-by-step explanation:
consider, cost of Fan = F and
cost of Watch = W
given that, the cost of a watch and fan is 3600, means
F+W = 3600................(1)
and the watch is 7 times the cost of fan, means
W = 7F ...............(2)
add equation (2) in equation (1)
F + 7F =3600
8F =3600
F=450 and W=3150
