The age of two people is in the ratio 6 8 the sum of their ages is 77 after 2

let their ages are x and y,
given x+y=77 and x:y=6:8
let x=6k and y=8k
therefore,
6k+8k=77 => 14k=77 =>k=5.5
=>x=6*5.5=33 , y=8*5.5=44
therefore there present ages are 33 and 44

Let their ages be 'a' and 'b' respectively.
Given: a/b = 6/8 = 3/4
a = 0.75b
Given: a+b = 77
So, 0.75b + b = 77
So, 1.75b = 77
So, b = 77/1.75 = 44
So, a = 77-44 = 33
But given: (a+2)/(b+2) = 5/7
But (a+2)/(b+2) = 35/46 ≠ 5/7
Question is ambiguous!

the 2nd ratio is incorrect..

by the way on cross multiplying we are not getting 2.we are getting -2. can u pls tell me the correct ans.

let two people be a,b a/b=6/8====>8a-6b=0===>4a-3b=0---->eq1
after two years a+2/b+2=5/7=====>7a-5b=-4---->eq2
on solving eq 1 and 2 we get ages a=12 and b=16
verification can be done by ratios(12:16=6:8(given i question))

PLZ EXPLAIN WHAT IS THE CORRECT ANSWER??

The ratio of two people be 6x and 8x
sum of their ages is 6x+8y=77
after 2 yrs,ratio is 5:7,so,
(6x+2)/(8x+2)=5/7
on cross multiplying this,
x=2
hence age of a person 6(2)=12
12+8y=77
8y=65
y=9(approx)

so the ages are 12,9

The age of two people is in the ratio 6:8. the sum of their ages is 77. after 2 years the ratio of their ages becomes 5:7. wat is their present age?
