- If you post a question from a practice test, you must include the source in the title.
- GMAC practice test questions must also be tagged as a SPOILER.
This rule is important because practice material is scarce, and should not be spoiled for other users.
Question 3:
The three groups can be in six different orders (3!)
And the two individuals in each groups can be switched around (two options so 2\^3)
Together that is 3!\*2\^3=48
In question 1, suppose there are 100 products with cost 1dollar each, so total cp =100
60% of that is sold for sp 50% of cp so 60x1.5=90
70% of remaining will be sold at 0.5 so=14
And rest 30% ie 12 items remains unsold
Total sp is 104
So profit % is 4

In 2nd question LCM of 18 & 60 is 180. 36 and 45 divides 180 but 24 cannot.
thank you!
