Since the difference between the price of an orange and a pear is the price of a banana, a banana is sold at $90 - $30 = $60. To buy 200 bananas, you'll pay $60 * 200 = $12000. When you twice as many oranges as bananas, you buy 2 * 200 = 400 oranges. The total cost of buying 400 oranges is 400 * 30 = $12000. The total price of buying 200 bananas and twice as many oranges as bananas is $12000 + $12000 = $24000.
Thus, the answer is 24000. <hau> Idan jimlar farashin lemu da pear ya kai dala 120, kuma pear ya kai dala 90, lemu ya kai dala 120 - dala 90 = dala 30.
