15. A sum of money is divided between Mohan and Sohan in the ratio 5 : 7. If Sohan's share is * 665,
find the total amount.
​

Answer 1

Step-by-step explanation:

Let the two numbers be 6x and 11x as their ratio is 6:11 Given 2 is added to first and 7 is added to second Hence the numbers become, (6x + 2) and (11x + 7) Given (6x + 2) : (11x + 7) = 8:15 Hence 15(6x + 2) = 8(11x + 7) 90x + 30 = 88x + 56 2x = 26 Therefore, x = 13 Hence the numbers are 6x = 6(13) = 78 11x = 11(13) = 143

Answer 2

Answer

Let the numbers be 3x and 5x.

Then , 5x+103x+10=75 or 7(3x+10)=5(5x+10)

∴4x=20orx=5

So, the numbers are 15, 25.
