Question

The ratio of ages of jay and joy is 5:2.Sum of their ages is 63.After 9 year what will the ratio of their ages?

Answer 1

Answer:

54 and 27

Step-by-step explanation:

Given- ratio of ages of Jay and Joy= 5:2

sum of their ages=63

Let the ratio of their ages be 5x and 2x

so, according to the question

5x+2x=63

7x=63

x=63/7

x=9

so, Jay's age= 5*9=45

Joy's age = 2*9=18

after 9 year Jay's age=45+9=54years

and, Joy's age = 18+9= 27years

Answer 2

$\boxed{GIVEN:-}$

Ratio of their present ages :- 8:5

Ratio of their ages after 6yrs :- 11:8

$\boxed{FIND:-}$

WE HAVE TO FIND THEIR PRESENT AGES....

$\boxed{SOLUTION:-}$

$let, \: their \: present \: ages \: be \: 8x,5x \\ \\ therefore \: after \: 8yrs \: there \: ages \: will \: be \: 8x + 6 ,5x + 6 \\ \\ so,8x + 6 \ratio5x + 6 = 11 \ratio8 \\ \\ \frac{8x + 6}{5x + 6} = \frac{11}{8} \\ cross \: multiply \: it \\ 8(8x + 6) = 11(5x + 6) \\ now \: solve \: it \: for \: value \: of \: x \: we \: have \\ x = 2 \\ so, \: present \: age \: jai = 8x = 8 \times 2 = 16 \\ present \: age \: of \: amy = 5x = 5 \times 2 = 10$
