Question

5 years ago santa bhai was 4 times as old as his daughter huku. 5 years later her age will be 6 more than 2 times huku age how old are they now

Answer 1

Answer:

Santa present age = 37

huku present age = 13

Step-by-step explanation:

let age of Santa be x

5 years ago his age was x - 5

5 years later his age will be x + 5

let huku age be y

5 years ago huku age was y - 5

5 years later her age will be y + 5

5 years ago Santa was 4 times older than huku

x - 5 = 4(y - 5)

x - 5 = 4y - 20

x - 4y = -15 equ (1)

5 years later Santa will be 6 more than 2times age of huku

x + 5 = 2(y + 5) + 6

x + 5 = 2y + 10 + 6

x - 2y = 11 equ (2)

multiply equ (2) with 2

2x - 4y = 22 equ (3)

subtract (3) - (1)

2x - 4y = 22

-(x - 4y = - 15)

x = 37

substitute x = 37 in equ (2)

x - 2y = 11

37 - 2y = 11

- 2y = 11 - 37

- 2y = - 26

y = -26/-2

y = 13

therefore Santa present age is x = 37

huku present age is y = 13

hope you get your answer
