Question

the answer is 240 but how pls solve my question ​

Answer 1

Step-by-step explanation:

Given that

X/Y =3/4

(x+20)/(y-40) =5/6

6x+120=5y-200

6x+120=5(4x/3)-200

-2x/3 =-320

X=960/2

X=480

X=240..

Hope it helps

Answer 2

Answer:

Hey mate , Here's your answer....

I will explain you ....

Answer :: Let the age common ratio be = X

Numerator = 3x

Denominator = 4x

So , Ratio = 3x / 4x .

Now, According to the Question --

(3x-4) / (4x-4) = 5/7

Cross multiplying....

7(3x-4) / 5(4x-4) ...This implies .

21x -28 =20x-20

or . X =8

Thus , Numerator = 3x = 3*8 =24

And , Denominator = 4x = 4*8= 32

So , Your answer is 24 : 32...
