Percentage P6 2010 SA2 CHIJ P2 Q16

Miss Flora had tulips, roses and carnations in her shop. In July, she sold a total of 1350 tulips, roses and carnations, of which 30% were tulips. There were as many roses as tulips sold. In August, the sale of carnations increased by 45%. This made up 27% of the total sales of tulips, roses and carnations. What is the percentage increase in the total sales of tulips and roses from July to August? (Leave your answer correct to 2 decimal places.)[5 marks][Answer given: 161.36%]



TJ --> 30/100 X 1350 = 405

RJ --> 405

405 + 405 = 810

CJ --> 1350 - 810 = 540

CA --> 145/100 x 540 = 783


27% --> 783

73% --> 73/27 x 783 = 2117

2117 - 810 = 1307


1307/810 x 100% = 161.36%

It was 161.36% increase.
