HEYA..

HERE IS YOUR ANSWER..

LET ..

THE PRESENT AGE OF A BE 'X'

AND PRESENT AGE OF B IS 'Y''

THEN A/Q..

X-Y= 16.........................[1]

AND

6 YR AGO

MEANS X - 6 = AGE OF X

Y - 6= AGE OF Y

2ND CONDITION-

X - 6 = 3 [Y-6]

= X-6 = 3Y-18

=X-3Y= -18+6

=X-3Y= -12.............[2]

THEREFORE BY ELIMINATION METHOD...

X - Y = 16

X -3Y = -12
- + +
________________-

2Y = 28

Y = 28/2

Y = 14..

PUT VALUE IN [1]

X-Y=16

X-14=16

THEREFORE X= 16-14

X= 2

SO AGE OF A= 14 YEARS..

AGE OF B = 2 YEARS


HOPE HELPED..

Heya,

ФФ→→ A तथा B में अंतर = 16.
 so,         A-B = 16            ___________1.
 
         A - 6 = 3B ___________________2.

USING  Elimination method .
               A  -3B   = 6 
               A -  B  = 16
              -    +       -                      (changing signs)
           __________________
            Then, 
      A -A -3B +B = 6-16
            -2B = -10 .
               B = 5 years .

then ,
 A -B = 16 
A = 16 + 5 
A = 21 .

HENCE , A = 21 years .
               B = 5 Years .
