C. $1.20 D.$1.32
E. $1.40 The OA is B Let x = Phil's money Sal has 20 percent LESS money than Phil So, Sal's money = (Phil's money) - (20% Phil's money) = x - (20% of x) = x - 0.2x = 0.8x Kim has 40 percent more money than Sal So, Kim's money = (Sal's money) + (40% Sal's money) = (0.8x) + (40% of 0.8x) = (0.8x) + (0.4)(0.8x) = 0.8x + 0.32x = 1.12x If Sal and Phil have a combined total of$1.80, how much money does Kim have?
We can write: 0.8x + x = 1.80
Simplify: 1.8x = 1.80
Solve: x = 1.80/1.8 = 1

We know that Kim's money = 1.12x
Since x = 1, we get: 1.12(1) = 1.12

Hi All,

We're told that Kim has 40 percent MORE money than Sal, Sal has 20 percent LESS money than Phil and Sal and Phil have a combined total of $1.80. We're asked for the amount of money that Kim has. This question can be approached in a couple of different ways, including some brute-force Arithmetic and logic. To start, we know the most about Phil and Sal, so we should think about a pair of values that would include a number that is 20% LESS than another number. Since we're dealing with dollars and cents, let's think about round-numbers just for a moment... What would we end up with if Phil had exactly$1.00?

20% of $1.00 =$0.20, so Sal would have $1.00 -$0.20 = $0.80 In this example, Phil + Sal would total$1.00 + $0.80 =$1.80... that's EXACTLY what the prompt tells us, so we now know exactly what Phil and Sal each have.

At this point, there's just one more step... Kim has 40% MORE money than Sal...
$0.80 + (4)($0.80) = $0.80 +$0.32 = $1.12 Final Answer: B GMAT assassins aren't born, they're made, Rich _________________ Contact Rich at Rich.C@empowergmat.com • Get 300+ Practice Questions 25 Video lessons and 6 Webinars for FREE Available with Beat the GMAT members only code • 1 Hour Free BEAT THE GMAT EXCLUSIVE Available with Beat the GMAT members only code • Free Veritas GMAT Class Experience Lesson 1 Live Free Available with Beat the GMAT members only code • 5 Day FREE Trial Study Smarter, Not Harder Available with Beat the GMAT members only code • FREE GMAT Exam Know how you'd score today for$0
