Hello @Varsha.

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

According to me, the solution is;

First, calculate the ratio= 1/2+2/3+3/4 = 23/12.
Now, we know the total is 782 Rs.
So the 1st part will be 783*1/2*12/23 = 204 Rs.

1/2:2/3:3/4.
6,8,9.
1st part , 782 * 6 / 23 = 204 ( simple answer).

Solution:

1/2 = 0.5, 2/3 = 0.67 , 3/4 = 0.75.
After this Let's consider common factor k, so this becomes,
0.5k, 0.67k , 0.75k.

Add this 0.5k + 0.67k + 0.75k = 782.
Find k -
k=407.29.

And we want to derive 1st no so put the value of k into 0.5k, which becomes
0.5 * 407.29= 203.64 ~ 204.

1/2 + 2/3 + 3/4 = 23/12 we are doing this because they gave a + b + c = 789.

So, we have to calculate a ,b , c values individually and at last we want a value so (a/total * given) == 1/2 (because we want 1st part value) ÷ 23/12 after solving this we get 6/23 now 6/23 * 789(given).

LCM OF 2,3,4 IS 12 THEN;

1/2 x 12 = 6 that's how it is done same to all u get.
6,8,9 then the sum of 8, 9, 6 is 23 that's how the answer comes first part 6/23 x 782 = 408.

1/2+2/3+3/4 = 23/12.
We need first part i.e 1/2.
1/2 * 12/23 * 782 = 204.
