Let the number of sunflower plants bought by Shila = x
Number of Rose plants bought by Shila = x + 35
According to the problem given ,
Ratio of Rose plants and Sunflower plants bought by shila = 8 : 3
( x + 35 )/x = 8/3
3( x + 35 ) = 8x
3x + 105 = 8x
8x - 3x = 105
5x = 105
x = 105/5
x = 21
Therefore ,
Number of sunflower plants bought by shila = x = 21
Number of Rose plants bought by shila = x + 35 = 21 + 35 = 56
