Question

the diff of two no.is 15 and their ratio is 3:2 find no.​

Answer 1

Step-by-step explanation:

Let one number be x and the other number be y

case 1:

x - y = 15 ------- (1)

case 2:

$x/y$ = $3/2$

2x = 3y

2x - 3y = 0 ---------------(2)

From (1) & (2),

x - y = 15 x2

2x - 3y = 0

⇒ 2x - 2y = 30

    2x - 3y = 0

(1) - (2)

∴ y = 30 ------------ (3)

substituting (3) in (1),

x - 30 = 15

x = 15 + 30

∴ x = 45

Let one number be x and the other number be y

case 1:

x - y = 15 ------- (1)

case 2:

x/y

= 3/23/2

2x = 3y

2x - 3y = 0 ---------------(2)

From (1) & (2),

x - y = 15 x2

2x - 3y = 0

⇒ 2x - 2y = 30

2x - 3y = 0

(1) - (2)

∴ y = 30 ------------ (3)

substituting (3) in (1),

x - 30 = 15

x = 15 + 30

∴ x = 45
