Question

in the ratio of 1:2 if 4 is added to each of them the ratio becomes 4:7 find the numbers​

Answer 1

Answer:

12 and 24

Step-by-step explanation:

Given ratio 1 : 2

Let the numbers be x, 2x

According to question if 4 is added

eachof them the ratio becomes 4 : 7

i,e ( x + 4 ) : ( 2x + 4 ) = 4 : 7

( x + 4 )/( 2x + 4 ) = 4/7

7( x + 4 ) =4( 2x + 4 )

7x + 28 = 8x + 16

7x - 8x = 16 - 28

-x = -12

x = 12

therefore the numbers are

x =12.

2x = 2 × 12 = 24.
