Question

Ramesh is 10 years older than karim. After 4 years ,twice Ramesh' s age will be equal to thrice Karim' age. How old are Ramesh and Karim at present​

Answer 1

Answer:

Karim is 7 years and Ramesh is 17 years

Step-by-step explanation:

let Kareem age be x

Ramesh is 10+ x years

After 4 years

2(10+4+x)=3(4+x)

20+8+2x=12+3x

20+8-21=x

7=x

Answer 2

Answer:

k=9yr

r=19 yr

--

Step-by-step explanation:

AS,r=K+10

(4+10)*2 = 3k

R=K+10

-10+R=K-10+10

so r-10=k

and 14*2=28=3k

hence, r-10=k and 28=3k , can be used to find the values of k and r through a simultaneous equation. i.e

k=r-10

28=3k

then , 28 = 3(r-10) which is 28=3r-30

28+30=3r

58=3r

r=58/3=19.333

r=19.33

k=19.33-10

ANSWER

k=9yr

r=19 yr
