Three numbers are in the ratio 4:3:5. If the difference between thrice...
Given: Three numbers are in the ratio 4:3:5
Let the three numbers be 4x, 3x, and 5x
Given: The difference between thrice the third number and the sum of first and second number is 64
Therefore, 3(5x) - (4x + 3x) = 64
Simplifying the above equation we get, 7x = 64
Hence, x = 64/7
Therefore, the three numbers are 4x = 256/7, 3x = 192/7, and 5x = 320/7
To find the difference between the first and third number, we need to subtract the first number from the third number
Therefore, (320/7) - (256/7) = 64/7
Therefore, the answer is 8 (Option B)
