Question

e) Rajat is 10 years older than Shree. 10 years from now, Rajat would be twice as
old as Shree was 10 years ago. How old would Shree be after 12 years?​

Answer 1

Answer:

see in your book ch-11 7th part

Answer 2

Solution:-

let rajay present age be x years

and shree age be y years

Then ;

x = y+10 ---------------------(i)

x+10=2(y-10)

x+10 = 2y- 20

x = 2y - 30 -----------------(ii)

Now compare the the equation (i) & (ii)

x=x

y+10= 2y-30

y = 40 yrs

Present age of shree = y = 40yrs

shree age after 12 yrs

= 40+12

= 52yrs
