(A) 20,000 (B) 22,000 (C) 25,000 (D) 30,000 (E) 40,000
Source NOVA Mr. Small = x; Mr. Middle = 3/2*x; Mr. Big = 2x. x + 3/2*x + 2x = 90 > x=20. Answer: A. Or plug in answer choices: C. If S=25, then M=37.5, and B=50 > the sum is more than 90. Try smaller numbers. B. If S=22, then M=33, and B=44 > the sum is more than 90. Try smaller numbers. A. If S=20, then M=30, and B=40 > the sum is 90. Answer: A. Hope it helps.

Source NOVA My brain processed it as follows: $90,000 = B + M + S B = 2S M = (3/2)S S = S Thus > 90,000 = 2S + (3/2)S + S Thus > 90,000 = (4/2)S + (3/2)S + (2/2)S (found lowest common denominator) Thus > 90,000 = (9/2)S Thus > 90,000 * (2/9) = S (took the reciprocal of 9/2 when dividing) Thus > 180,000/9 = S Thus > S = 20,000 Might be slower but helps me to get terms I can combine.

B + S + M = $90,000 B = 2S M = 3S/2 2S + S + 3S/2 = $90,000 4S + 2S + 3S = $180,000 S = $180,000/9 = $20,000. Ans  A.

The combined salaries of three brothers is $90,000. Mr. Big earns twice what Mr. Small earns, and Mr. Middle earns 1 1/2 times what Mr. Small earns. What is the smallest salary of the three brothers?Let the salary for Mr. Small be \(x\) \(2x + 1.5x + x = 90,000\) \(4.5x = 90,000\) \(x = 20,000\) Hence, Answer is A

(A) 20,000 (B) 22,000 (C) 25,000 (D) 30,000 (E) 40,000 We can let the salaries of Mr. Big, Mr. Small, and Mr. Medium = B, S, and M, respectively, and create the equations: B + S + M = 90,000 and B = 2S and M = 1.5S Substituting, we have: 2S + S + 1.5S = 90,000 4.5S = 90,000 S = 20,000 Answer: A
