Question

The ration of two number is 3: 5. if both numbers are increased by 5 their ratio becomes 2:3 find no​

Answer 1

Answer:

let the no be 3x and 5x

then,

3x+5 / 5x+5 = 2/3

2(3x+5) = 3(5x + 15)

6x + 10 = 15x - 15

6x - 15x = 15- 10

9x = 5

x = 5/9

now,

3x= 3 × 5/9. = 15x/9

5x = 5 × 5/9 = 25/9
