Solution

The correct option is B 300 dollars
Roses Garland:–––––––––––––––
Number of flowers in garland = 20
Cost of each flower = 15 dollars
Cost of roses garland = 20×15=2×15×10=300 dollars

Lilies Garland:––––––––––––––
Number of flower in garland = 15
Cost of each flower = 20 dollars
Cost of lilies garland = 15×20=20×15=300
(By commutative property 15×20=20×15=300)

Therefore, Cost of each garland = 300 dollars
(b) is the correct option
