Morning,
Janelle went to a florist to buy some flowers. She spent 1/6 of her money on q bouquet of roses and $154 on a bouquet of lilies. She spent 1/9 of her remaining amount on a bouquet of carnation flowers. If the amount of money left was $240 more than 1/4 of the amount she had at first, how much had she left? :?

Hi

Just to confirm, is it 'Total area of X and Y is equal to 3/4 of Z\" or \"Total area of X and Z is equal to 3/4 of Y\"

Best wishes

If this question been posted before, sorry for posting here again. But could someone help to confirm the answer as there is no solution given but only suggested answer is 0954h. Question from CHIJ 2011 Prelims.


Ans : A rectangular tank measuring 40cm by 30cm by 40cm was 1/6 filled with water. At 0930h, Tap X waith water flowing out at a rate of 3 litre per minute was turned on.
At 0932h, Tap Y was turned on to drain water out of the tank at a fixed rate.
At 0943h, the tank was 75% filled with water.
At what time would the tank be filled to the brim ?
