A department manager distributed a number of pens,
pencils, and pads among the staff in the department,
with each staff member receiving x pens, y pencils,
and z pads. How many staff members were in the
department?
(1) The numbers of pens, pencils, and pads that
each staff member received were in the ratio
2:3:4, respectively.
(2) The manager distributed a total of 18 pens,
27 pencils, and 36 pads.
my answer is C , OG answer is E,
If the ratio is 2:3:4, then implies the total be 9x items. from statement 2 total is 81,hence X = 9
so 9 people.Am i going wrong some where

think about it like this. if C. The following scenarios are possible: if 1 employee: each receives 18 pens,27 pencils, and 36 pads., and the ratio is 2:3:4 if 3 employees: each receives 6 pens,9 pencils, and 12 pads. and the ratio is 2:3:4 if 9 employees: each receives 2 pens,3 pencils, and 4 pads, and the ratio is 2:3:4 Multiple solutions are possible, thus E.

Be careful, those are the ratios, not the actual number of items each person received.

The question does not specify how many staff member received how many pen, pad etc., so mere ratios of the stationeries can't help in finding the number of staff. Answer - E.

the answer is E as the number of pens,pencils and pads each person received is unknown and so is the total number of people.

the trick of this question is in that multiple possiilities are availabel within given data. If they would provide us other ratios like 2:7:11 and the number of distributed things which would rise unique possible combination the answer would be C. Don't think the information is not available untill you carefully analysed all available data.

so 9 people.Am i going wrong some where Only ratios are provided but number of persons are provided against the ratios so that we calculate total number of staffs.
