Answer 2

7200

Step-by-step explanation:

If one Orange cost 60 rupees then the cost of 1 dozen oranges are 12*60 =720

If one mango cost 40 rupees then the cost of one dozen mangoes are 12*40=480

if one banana cost 30 rupees then the cost of 1 dozen of bananas are 12*30=360

Therefore,the value of of the fruits in the shop =

Cost of Oranges+Cost of Mangoes +Cost of Bananas.

=(720*5)+(480*3)+(360*6)

=3600+1440+2160

=7200
