The ratio of A, B, C and D in X, Y and Z is given to be
Since 1 unit of M has 3X, 4Y and 6Z, we can show the contribution of A, B, C and D in 1 unit of M or 3 units of X, 4 units of Y and 6 units of Z.
Therefore 1 unit of M has 147/60​ units of A, 201​/60 units of B, 12/5​ units of C and 24/5​ units of D.
Also, the total quantity of 1 unit of M= (3+4+6) units= 13 units.

Given information:
- 1 unit of M consists of 3 units of X, 4 units of Y, and 6 units of Z.
- 1 unit of X is made by A and B in the ratio 5:7.
- 1 unit of Y is made by B and C in the ratio 2:3.
- 1 unit of Z is made by A and D in the ratio 1:4.

We need to find the approximate percentage contribution of A in 1 unit of M.

Let's first calculate the total contribution of A in 1 unit of X:
- Since 1 unit of X is made by A and B in the ratio 5:7, we can say that A contributes (5/12)th of 1 unit of X.
- Therefore, the contribution of A in 1 unit of X is (5/12) * 1 = 5/12.

Now, let's calculate the total contribution of A in 1 unit of Y:
- Since 1 unit of Y is made by B and C in the ratio 2:3, we can say that B contributes (2/5)th of 1 unit of Y.
- Therefore, the contribution of B in 1 unit of Y is (2/5) * 1 = 2/5.
- Now, since 1 unit of Z is made by A and D in the ratio 1:4, we can say that A contributes (1/5)th of 1 unit of Y.
- Therefore, the contribution of A in 1 unit of Y is (1/5) * 1 = 1/5.

Now, let's calculate the total contribution of A in 1 unit of Z:
- Since 1 unit of Z is made by A and D in the ratio 1:4, we can say that A contributes (1/5)th of 1 unit of Z.
- Therefore, the contribution of A in 1 unit of Z is (1/5) * 1 = 1/5.

Now, let's calculate the total contribution of A in 1 unit of M:
- 1 unit of M consists of 3 units of X, 4 units of Y, and 6 units of Z.
- Therefore, the contribution of A in 1 unit of M can be calculated as:
(Contribution of A in 1 unit of X * Number of units of X in 1 unit of M) +
(Contribution of A in 1 unit of Y * Number of units of Y in 1 unit of M) +
(Contribution of A in 1 unit of Z * Number of units of Z in 1 unit of M)

= (5/12 * 3) + (1/5 * 4) + (1/5 * 6)
= 15/12 + 4/5 + 6/5
= 5/4 + 4/5 + 6/5
= (25 + 16 + 24) / 20
= 65 / 20
= 13 / 4

Therefore, the approximate percentage contribution of A in 1 unit of M is:
(Contribution of A in 1 unit of M / Total units in 1 unit of M
