Question

13. Two numbers are in the ratio 2:3. If 4 be subtracted from each they are in the ratio of 3:5. The numbers are
​

Answer 1

Step-by-step explanation:

let 1st no = 2x

let 2nd no = 3x

2x-4/3x-4=3/5

5(2x-4)=3(3x-4)

10x-20=9x-12

x=8

so 1st no = 2×8=16

2ND NO IS 3×8=24

Answer 2

Answer:

Let the number is

2x : 3x

4 is subtracted

(2x - 4) : (3x-4)

(2x - 4) /(3x-4) = 3/5

5(2x - 4) = 3(3x-4)

10x - 20 = 9x -12

10x - 9x = -12 + 20

x = 8

Number is

2x : 3x

2x = 2 x 8 = 16

3x = 3 x 8 = 24
