The sum of three numbers is 98. the ratio of the first to the second is 2 on 3, and the ratio of the second to the third is
Answers
Answer:1/3
Step-by-step explanation:as 98
Is only divisible by 1,7 , 14 , 49 , 98
So the ratio of three no's should be these no...
Here
1. If we take 7 so 3rs no. Should be 2x and ratio should be 3/2 and I don't think 2 no.s would be same so.. Not this
2. If we use 14 it's give 3rd no. As 9x and answer should be 3/9 = 1/3 ..
3. If we use 49 so 3rd no. Should be 44x and and ratio would be 3/44 .. Which is highly unlikely..
So my guess would be 1/3 ..
But there is something missing in the question.. But these r the only options which could be so...
So something is missing
Answer:
Step-by-step explanation:
Solution:
Let the three numbers be x, y and z.
Sum of the numbers is 98.
x + y + z = 98………………(i)
The ratio of the first to the second is 2/3.
x/y = 2/3.
x = 2/3 × y.
x = 2y/3.
The ratio of the second to the third is 5/8.
y/z = 5/8.
z/y = 8/5.
z = 8/5 × y.
z = 8y/5.
Put the value of x = 2y/3 and z = 8y/5 in (i).
2y/3 + y + 8y/5 = 98
49y/15 = 98.
49y = 98 × 15.
49y = 1470.
y = 1470/49.
y = 30 .
Therefore, the second number is 30.
