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?
Answer & explanation
Correct answer: option 3
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
