Your answer is

If each number in increased by 10, the ratio between the new number so formed is 5 : 7. A/Q, ∵ ( x + 10 ) : ( y + 10 ) = 5 : 7 . ⇒ 7( x + 10 ) = ( y + 10 ) 5 .

Answer 2

Answer:

15,25

Step-by-step explanation:

as the two numbers are in 3:5 ratio lets take them as 3x& 5x

if we increase them by 10 we get the numbers 3x+10 & 5x+10

these numbers are in 5:7 ratio

so,we can say3x+10 /5x+10= 5/7

then by cross multiplication we get

21 x +70=25x +50

70-50=25x-21x

20=4x

5= x

then the numbers are 15 and 25
