Given:
The ratio of compound in 4:5
The duplicate of a:9 is 8:15
To find: The value of a
Solution:
Let the compound be 4x and 5x
Let the value of a be y
Then 2a = y
The duplicate of a:9 is 8:15
Therefore, (2a)*2:9*2 = 8:15
2y:18 = 8:15
y:9 = 4:15
y = (4/15)*9
y = 12/5
2a = 12/5
a = (12/5)/2
a = 12/10
a = 6/5
Therefore, the value of a is 6/5 or 1.2
Hence, option (a) 2 is incorrect and the correct answer is option (d) 5.
Note: The solution involves using the concept of ratios and proportions. The given ratios are equated to find the value of 'y', which is then substituted to find the value of 'a'.

4/5 × √a/√9 = 8/15
5 × 3 = 15
4 × 2 = 8
so, √a = 2
then, a = 4
5 × 3 = 15
4 × 2 = 8
so, √a = 2
then, a = 4
