Q:
A) 4:6:8 | B) 4:7:8 |
C) 4:8:16 | D) 4:9:16 |
Answer: D) 4:9:16
Explanation:
Explanation:
Let their investments be Rs. x for 12 months, Rs. y for 8 months and Rs. z for 6 months respectively.
Then, 12x : 8y : 6z = 4 : 6 : 8
Now, 12x/8y = 4/6 <=> 9x=4y <=> y=9x/4
And, 12x/6z = 4/8 <=> 4x=z <=> z=4x
Therefore, x : y: z = x : 9x/4: 4x = 4 : 9 : 16
