Answer 1

Answer:

Let +ve no is =X

Other is Y

Then

X=7Y

&

X+25 : Y+25 = 1 : 2

(X+25) / (Y+25) = 1/2

2X+50 = Y+25

14Y+50 = Y+25

14Y- Y= - 25

13Y = - 25

Y= -25/13

X=7*(-25/13)

= - 175/13

Answer 2

Answer:

Answer:35

Step-by-step explanation:

let number be x

therefore other number is 7x

given,

(x+25) : (7x +25) = 1:2

=> (x+25) ÷ (7x+25) = 1/2

=> 2(x+25) = 7x+25

=> 2x+50 = 7x+25

=> 50-25 = 7x-2x

=> 5x= 25

=> x=5

so required positive number= 7x = 35
