The number of red, white and yellow flowers are 315, 420 and 315 respectively.
Red = 3/10 × 1050
= 3,150/10
= 315
White = 2/5 × 1050
= 2,100/5
= 420
Number of yellow flowers = Total - (red + white)
= 1,050 - (315 + 420)
= 1,050 - 735
= 315 flowers
Therefore, the number of red, white and yellow flowers are 315, 420 and 315 respectively.
