Question

2. The ratio of ages of jack and sill is 4:3 the product their ages in 432 what will be the ratio of their ages after 18 years

Answer 1

Answer:

Step-by-step explanation:

Let jacks age be x And,

Let jills age be y

x:y::4:3

OR,

x/y=4/3

Cross multiplying...

y=3x/4    -----------(i)

Product of ages is 432

x.y=432

Putting y=3x/4 from (i) in above equation

x.3x/4=432

$3x^2 /4 =432$

$x^2=432X4 /3$

$x^2=576$

therefore, x=+24 (as age can't be negative)

therefore,y=18
