Can you help me with this problem: Elena and Jada both read at a constant rate, but Elena reads more slowly. For every 4 pages t
Paraphin [41]

4 pages Elena = 5 pages Jada

To figure out how many pages Jada reads if Elena reads 1, divide 5 by 4: 1.25. This means that for every 1 page Elena reads, Jada reads 1.25 pages.

So if Elena reads 9 pages, multiply 1.25 by 9: 11.25 pages that Jada reads.

For S pages read by Elena, this is a variable, so I’m assuming it means for every S pages, Jada reads 1.25S

. Find their present ages. 6 years ago a man's age was six times the age of his son. 4 years hence, thrice his age will be equal
ddd [48]

<u>The present age of the man is 36 years and his son is 11 years.</u>

Answer:

Solution given:

let the age of man be x.

and his son be y.

By question

x-6=6(y-6)

x=6y-36+6

x=6y-30. ......(1)

and

3(x+4)=8(y+4)

3x+12=8y+32

3x=8y+32-12

3x=8y+20. ...(2)

substituting value of x in equation 2 ,we get

3(6y-30)=8y+20

18y-90=8y+20

18y-8y=90+20

10y=110

y=110/10

y=11 years

again substituting value of y in equation 1 we get

x=6*11-30

x=66-30

x=36 years
