1250 is divided into four parts such that 4 times the first part, 3 times the second part, twice the third part are all equal to the fourth part. Find the difference between the 2nd and 3rd part.

A.	100	B.	400
C.	150	D.	50

Answer and Explanation

Answer:100

Explanation:
Let the parts be U, V, W, X
U + V + W + X = 1250 =>(1)
4U = 3V = 2W = X
U = X/4, V = X/3, W = X/2
Substituting in 1 we get,
(3X + 4X + 6X + 12X)/12 = 1250
25x/12 = 1250
x= 120 Ã—12 / 25 = 600
U = 600/4 = 150 ; V = 600/3 = 200; W = 600 / 2 = 300 and X = 600
300 - 200 = 100
