The following bar chart shows the number of flowers (in '000 kg) grown by a floriculturist in 5 consecutive years?

The number of flowers grown in Y5 was 15% more than those grown in Y4. The number of flowers grown in Y6 was 20% more than those grown in Y5. What is the difference between the numbers of flowers grown in Y9 and Y4?

154000

15% = \(\frac{3 }{20}\) &  20% = \(\frac{1 }{5}\)

Ratio of   ,

   Y4  :  Y5

= 20  :  23

&  Y5   :   Y6

=   5    :   6

Overall , Y4  : Y5  : Y6 = 100 :  115  :  138

ATQ ,

138R = 345000

1R = 2500

Y4 = 100R = 250000

and Y9 = 404000

Difference in Y4 & Y9 = 404000 - 250000 = 154000
