Here is complete explanation of Of the four numbers the first is twice the second the….

Solution(By ExamCraze Team)

Let the fourth number be x
Then, third number = 5x
Second number = $$frac{5x}{3}$$ and
First number = $$frac{10x}{3}$$
x + 5x + $$frac{5x}{3}$$  + $$frac{10x}{3}$$   = (24.75 × 4)
⇒ 11x = 99
⇒ x = 9
So, the numbers are 9, 45, 15 and 30
∴ Largest number = 45
