Question

the age of hari and harry are in the ratio 4:6 four years from now the ratio of their ages will be 4:5 find the present age of hari​

Answer 1

Answer:

Present age of hari is 4years

Step-by-step explanation:

let the present ages of hari and harry be 4x and 6x respectively.

4x+4÷6x+4=4/5

now cross multiply

20x+20=24x+16

4x=4

X=1

Present age of Hari =4x

4×1

4 years

Answer 2

Answer:

hari age is 4 years and Harry age is 6 years

Step-by-step explanation:

let the age of hari be x and age of Harry be y

x/y =4/6

6x -4y=0. (1)

four years from now their age ratio is

x+4/y+4 =4/5

4y +16=5x +20

5x -4y =-4. (2)

By solving equation 1 and 2 we get

x=4

by putting the value of x in equation 1

y=6
