"A)Rs.390",
"B)Rs.368",
"C)Rs.380",
"D)Rs.360"
] | D | Let the shares of A, B and C be a, b and c respectively.
a : b : c = 1/2 : 1/3 : 1/4
Let us express each term with a common denominator which is the last number divisible by the denominators of each term i.e., 12.
a : b : c = 6/12 : 4/12 : 3/12 = 6 : 4 : 3.
Share of C = 3/13 * 1560 = Rs. 360.

I. x = 1
II. y = 0
III. x = 0 | [
"A)I only",
"B)II only",
"C)III only",
"D)I and III only"
] | C | Answer choice A is correct.
The question gives you x^2=xy
you can simplify that as x^2-xy=0
x(x-y)=0 the solution will be either x=0 or x=y, since x and y are different integers x cannot equal y, that leaves you x=0 to be the only answer.
