Answer 1

Answer:

Step-by-step explanation:

2nd number: 3rd number is =6:5=6/5

1st number: 2nd number is =3:7=3/7

The value of second number in each equation are different.

So let's multiply the 6/5 with 7 up and down.

6×7/5×7=42/35. 42 second number and 35 thrid number.

Now let's multiply 3/7 with 6 up and down.

3×6/7×6=18/42. First number 18 and second number is 42.

Values of 2nd number in both equation are now same. Which is 42.

1st number:2nd number:3rd number=18:42:35.

Let's take 'a' as common factor.

So 18a+42a+35a=285

Therefore, a=3

Now the 3rd number is 35a.

35a=35×3=105
