Given data.
1/2 : 2/3 : 3/4 = 782.
=> (1/2)x:(2/3)x:(3/4)x = 782.
=> x/2 + 2x/3 + 3x/4 = 782.
L.C.M(2,3,4) = 12.
(6x+8x+9x)/12 = 782.
23x = 782 * 12.
x = 9384/23.
X = 408.
First part= (1/2) * 408 = 204.
1/2 : 2/3 : 3/4 = 782.
=> (1/2)x:(2/3)x:(3/4)x = 782.
=> x/2 + 2x/3 + 3x/4 = 782.
L.C.M(2,3,4) = 12.
(6x+8x+9x)/12 = 782.
23x = 782 * 12.
x = 9384/23.
X = 408.
First part= (1/2) * 408 = 204.

Given ratio = : : = 6 : 8 : 9.
1st part = Rs. 782 x 6 = Rs. 204.
1st part = Rs. 782 x 6 = Rs. 204.

Given by 3 ratios into divided by some parts like 1/2 is the 1st part, 2/3 is the 2nd part,3/4 is the third part so,
We are talking 3 parts 1st we should follow L.C.M 2,3,4 = 12 so,
1/2 * 12 = 6(1st), 2/3 * 12 = 8(2nd), 3/4 * 12 = 9(3rd) then we adding those values 6 + 8 + 9 = 23 then now they are asking abt 1st part /total ratio*some money(Rs).
6/23 * 782 = 204.
So, the ans is [D].

782 is divided into three parts A shares 1/2 which means half of 782.
I am Confused, please help me out.

1st take the LCM of all denominators i.e 2,3,4 is 24 then multiply each ratio by 24. 1/2*24=12 , 2/3*24=16, 3/4*24=18.
Therefore ans is 12:16:18.
i.e 6:8:9. That's over
