DIPAK KUMAR BHAGAT  (10 years ago)

let ages are, 6x & 5x.
so,according to prblm;
6x+5x=44
x=4
then present ages are, 24 & 20
again let after y yrs the ratio will be 8:7
therefore, (24+y)/(20+y)=8/7
solving the equation we get, y=8
so,ans is 8 yrs.

SHARDA VISHWAKARMA  (10 years ago)

we take two people x and y than
x/y=6/5
x+y=44
than y=20,x=24,now we take after a year
24+a/24+a=8/7
than x=8 ater 8 years ratio between x and y would be 8/7
ans:8

11x=44
>> x=4
24 30
after 8 yrs

sasirekha  (10 years ago)

since the ratio is 6:5,
thus 6x+5x=44
11x=44
x=4.
The exact value of 6:5 would be 24 : 20
And thus for 8:7 ,the common value to be multiplied is same.,
so for 8:7 -> 8(5):7(5)-> 32:28.
On finding the difference between their ratio values,it is 8.
Hence the answer is 8

Priyanka Choudhary  (10 years ago)

let the ages be 6x and 5x
then 6x+5x=44
so x=4
so age of 1st person=6*4=24
age of 2nd person=5*4=20
now let the number of years be y, then
(24+y)/(20/y)=8/7
Solving this we get y=8
so after 8 years their ratio will 8:7
ans:8

mina shivaji mundhe  (10 years ago)

ans-8
let, 6:5 as 6x and 5x
so 6x+5x=44 ,x=4 and 6x=24 and 5x=20
now let,after y years ratio would be 8:7
so (24+y)/(20+y)=(8/7)
y=8

ANGELIN ALFRED  (10 years ago)

let the two people be A and B
GIVEN: A+B=44
A:B=6:5 => (A/B)=(6/5) => A=(6B/5)
SOL: A+B =44
((6B/5)+B)=44 => B=20 and A=44-B=44-20=24
A=24 and B=20
let x years hence their ratio becomes 8:7
(A+x):(B+x)=8:7
=> ((24+x)/ (20+x))=(8/7)
=> x= 8
therefore, after 8 years their ratio becomes 8:7

Suman Saurabh  (10 years ago)

let ages are, 6x & 5x
so, 6x + 5x = 44
x=4
So current ages is 24 & 20.
let y years after ratio becomes 8:7
(24+y)/(20+y)=8/7
so y = 8 years

Kundan Dhande  (10 years ago)

Let x be the common factor.
therefore 6x+5X=44
i.e. 11x=44 therefore x=4
So their ages are 6*4=24 and 5*4=20
now as their ages are 24 and 20 le us consider after x years their
age ration will be 8:7
then the equation becomes: (24+x)/(20+x)=8/7
then value of x=8.
Therefore after 8 years the ration would be 8:7

jaffreyhudson  (10 years ago)

the age is 24 AND 20
(24+x)/(20+x)=5/8
solving x = 8 years

Is this solution Helpfull? Yes | No   

KALIDASS  (10 years ago)

Ans:8 years
let the year be x.Then 6x+5x=44.
x=4.the two peoples ages are 24,20.
now (6x+2x)/(5x+2x)=8x/7x=8:7.so year to be add is 2x=8.

Shanmugavalli  (10 years ago)

24:20=6:5
so
after 4 years 8:7

vinod  (10 years ago)

6X+5X=44 ==> X=4
Ages are 24,20
After 8 years ages are 32 28
their ratios are 8:7
