C) Quantity I < Quantity II D) Quantity I < Quantity II
 
Answer & Explanation Answer: C) Quantity I < Quantity II

Quantity I= Let the three numbers will be 5x, 6x and 10x respectively

ATQ

10x+5x−6x=126 

9x=126 X=14

So largest number =10x=10×14=140

Quantity II=let x and y are two numbers

ATQ 

12% of x=25%of y And their difference is 78 

So first no.=150 2nd no.=72

Hence Quantity I < Quantity II
