Rs 11,550 has to be divided between X, Y & Z such that X gets 4/5 of what Y gets and Y gets 2/3 of what Z gets. How much more does Z get over X (in Rs)?
given X=(4/5)Y Y=(2/3)Z Z=(3/2)*(5/4)Y Z=15X/8 X+Y+Z=11550 X+(5/4)X+15X/8 =11550 33X/8 =11550 X=11550*8/33 X=2800 Z=15X/8 Z gets 7X/8 =7*2800/8 =2450
