Hello,
The ratio of efficiency is A : B : C is 4: 5 : 6
Let work done is unity.
So, the total work done is 4x+ 5x + 6x = 1
So, x = 1 / 15
Hence, the total fraction of work done by A = 4x = 4 / 15
Talking percentage wise, Work Done by A = 4 x 100 / 15 %
So, Work Done by A = 26.67%
Best Wishes.
Since they completed the job together there amount of job done will be in the ratio of their efficiency that is 4:5:6.
Now the fraction of job done by P is 4/4+5+6
That is 4/15
If something is not clear mention in the comments.

Question : Partners P, Q, and R split earnings in the following proportions: 7: 5: 3. When P retires, it is decided that Q and R will share profits at the same ratio as P and Q did. Calculate the Gaining Ratio and the New Profit-Sharing Ratio.
Option 1: New Ratio between Q and R is 7 : 5
Gaining Ratio between Q and R is 8 :7
Option 2: New Ratio between Q and R is 2 : 3
Gaining Ratio between Q and R is 13 : 15
Option 3: New Ratio between Q and R is 7 : 5
Gaining Ratio between Q and R is 15 : 18
Option 4: None of the Above

Option 1: $2 \frac{7}{18}$
Option 2: $1 \frac{7}{18}$
Option 3: $1 \frac{6}{19}$
Option 4: $2 \frac{6}{19}$
