At first to take lcm 2:3:4 then the result is 12.
Then after multiplying 1st part 1/2 * 12 = 6.
After multiplying 2nd part is 2/3 * 12= 8.
After multiplying 3rd part is 3/4 * 12 = 9.
The result is 6 : 8 : 9 after the result add it (6 + 8 + 9) = 23.
According to question find the 1st Part.
1st part is 6 and the total number is 23.
ie, 782 * 6/23 = 204 is the correct answer.
Then after multiplying 1st part 1/2 * 12 = 6.
After multiplying 2nd part is 2/3 * 12= 8.
After multiplying 3rd part is 3/4 * 12 = 9.
The result is 6 : 8 : 9 after the result add it (6 + 8 + 9) = 23.

How 6:8:9?

Since the ratio is 6:8:9 = 23.
So, first part = 6/23,
Second part = 8/23,
Third part = 9/23,
We have to find the first part therefore 6/23.
So, first part = 6/23,
Second part = 8/23,
Third part = 9/23,
We have to find the first part therefore 6/23.

Given:- Amount = Rs. 782.
Ratios = 1/2:2/3:3/4.
Add the given ratios = 1/2+2/3+3/4 = 23/12.
To find the first part = given amount * first part ratio/total value of the ratios.
= 782*[ (1/2) / (3/4) ].
Answer = 204.
Ratios = 1/2:2/3:3/4.
Add the given ratios = 1/2+2/3+3/4 = 23/12.
To find the first part = given amount * first part ratio/total value of the ratios.
= 782*[ (1/2) / (3/4) ].
Answer = 204.

Given 1/2, 2/3, 3/4.
The first part 1+2, 2+3, 3+4 (add).
3, 5, 7, the total : 15.
1/2*15 = 7.5.
2/3*15 = 10.
3/4*15 = 11.25.
This total : 28.75.
And 7.5/28.75*782 = 204.
We want first one so first one is 204.
So answer is 204.
The first part 1+2, 2+3, 3+4 (add).

Just simple calculation 1/2+2/3+3/4 = 23/12.
23/12 = 782.
1/2 = ?
782*1/2*12/23 = 204.
23/12 = 782.
1/2 = ?
782*1/2*12/23 = 204.
