Question

a positive number is 7 times another number if 25 is added to both the numbers the ratio is 1:2 find the number
, ​

Answer 1

Answer:

Let the two numbers be x and 7x

On adding 25,

x+25 - - - (I)

7x + 25 - - (ii)

According to the problem,

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

=> 2x +50 = 7x + 25

=> 25 = 5x

=>x=5

Therefore the +ve number is 5 and the other number is 35.

Answer 2

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
