Solution
The correct option is B 440 Given,
Prices of the ornaments = 226 dollars + 134 dollars + 74 dollars + 6 dollars
Sum = 226 + 134 + 74 + 6
The numbers 226 and 74 make 300 on adding.
The numbers 134 and 6 make 140 on adding.
Then, adding 300 and 140, we get:
300 + 140 = 440
Therefore, the sum of the cost of the ornaments is 440 dollars.
