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].

Hello @Varsha.
Take LCM of 3 we get 12 that's it.

6 : 8 : 9 ?
6/8 = 9/x.
6x = 9×8.
x = 9×8/6.
x = 12.
6/8 = 9/x.
6x = 9×8.
x = 9×8/6.
x = 12.

In wat way the ratio 1/2 : 2/3 : 3/4 is written as 6:8:9 ?

Multiply 1/2 with 6, 2/3 with 4 and 3/4 with 3 so that numerator is same i.e. 12, hence 6:8:9
First part is 6 upon sum of 6+8+9=23 i.e. 6/23
First part is 6 upon sum of 6+8+9=23 i.e. 6/23

How 1/2 is attained as 6 2/3 as 8 and 3/4 as 9 and how for calculating the first part the number is multiplied by 6/23 ?

The LCM of all the denominators is 12. So multiply the number and denominator with 6 to make 1/2 as 6/12, multiply 2/3 with 4. So that it becomes 8/12 and multiply 3/4 with 3 to make 9/12. Now the new ratio will be:
6/12, 8/12, 9/12.
Now cancelling 12 we will get 6, 8, 9.
6/12, 8/12, 9/12.
Now cancelling 12 we will get 6, 8, 9.

You just need to multiply every ratio by 12 because it is the lcm of denominators.
