Guess-and-check would usually involve 2 items. As there are 3 items here, you can do grouping i.e. 1 group (T+H+C) = $1.50 No of groups = 8/1.5 approx 5 5 groups = 5 x 1.5 = 7.5 Rem = 8 - 7.5 = 0.5 (heart-shaped) hence, there are 5 triangular, 5 cylindrical and 6 heart-shaped.

Tnx! But sounds complicated. Is a P3 student expected to know this grouping method?

Since total is $8, H will be an even number. Avg price is $0.50. Assuming H is 16 to begin with. A reduction of 2H will be an increase in 1T and 1C since we still want to maintain the avg of $0.50. Hence, there are many combinations to the answer. 14H/1T/1C, 12H/2T/2C, 10H/3T/3C, 8H/4T/4C, 6H/5T/5C, 4H/6T/6C, 2H/7T/7C. (0H/8T/8C and 16H/0T/0C are not part of answers since it says different types were sold )

Hope I am not interpretating wrongly.

Answer could also be 6 triangle ... 4 hearts ... 6 cylinder

Thanks ☺

If 1/3 of the pupils move from group A to B then Grp A should have pupil multiple of 3

4 out of 5. therefore it's 4u. 1/5 of the concentrate's syrup and 4/5 of it's water.

It's a pretty tough question. Did the teacher provide the answers?

Honestly..with due respect to the author whom most of us know..the question is set with some ambiguity. 1/5 of the concentration was syrup...this section is not clear and can lead to different interpretations...

I got it now. Because of the phrase 'of the concentration was syrup' means syrup 1U and water 4U. I was confused earlier on coz I have another similar question but doesn't require to minus the changed item. Now I realized that question use as many as whereas this one use of the .... So confusing. Thank you Elaine Eo.

It's all in the English...
