Question

The sum of the present ages of Mr.X and Mrs.Y is 123 years .Four years hence the age of Mr X will be 6 years more than one and a half times the age of Mrs.Y .(after 4 years). Find their present ages. Who is Mr
X (A bollywood celebrity)​

Answer 1

Answer:

77,  46

Step-by-step explanation:

Let present age of Mr.X be 'X'

         present age of Mr.Y be 'Y'

X + Y = 123...... 1

After 4 years

 both Mr.X and Mr.Y will grow 4 years

(X+4) = 6 + (1/2)(Y+4)

2X -Y = 8...... 2

Solving these equations,

 X = 77, Y= 46

X is Amitabh Bhachan

 

Answer 2

Answer:

 

Step-by-step explanation:

X + Y = 123   .............(1)

after 4 years

x+4....Ms X

Y+4 = 3/2 (y+4) + 6

so X+4 = 3y/2 +(3X4)/2 + 6

X+4 = 3y/2 + 6 +6

X+4 = 3y/2 + 12

multiply whole equation by 2

2x +8 =3y  +24

2x -3y = 24 - 8

2x -3y = 16................... (2)

multiply eq (1) by 2

2x +2y = 246...............(3)

eq (3) take away eq (2)

2x -2x +2y-(-3y)  = 246-16

+5y = 230

y =  230/ 5=46     and from (1)........ x  =  123-46= 7 7

Mr X = 77   and Ms Y = 46

77 + 4 = 81

46 +4= 50

one and half times 50  is 75  plus 6 equals 81
