Question

In an empty field, 180 tulips and 220 azaleas have been planted. If 270 more tulips are going to be planted, how many more azaleas must be planted so that 4/9 of the flowers in the field are azaleas?
steps

Answer 1

Initially,
No. of tulips = 180.
No. of azaleas = 220
Now, after planting 270 tulips more
No. of tulips = 180+270 = 450.
Let the number of azaleas be x.
As per the question,
4/9 of total flowers = no. of azaleas
4/9* (450 + 220+x) = 220+x
4/9 * (670+x) = 220+x
2680 + 4x = 1980 +9x
5x = 700
x= 140
So, No. of more azaleas to be planted is 140.
