numbers?

(c) 1001 (d) 1100​

Answer 1

Answer:

6,9

Step-by-step explanation:

let three years ago age of Raji=X

then age of raju=2X

after three years

age of Raji=X+6

and age of raju=2X+6

as 2X+6=4/3(X+6)

6X+18=4X+24 (cross multiple)

6X-4X=24-18

2X=6

X=3

then age of Raji 3 years ago=3 years

and age of raju 3 years ago=3*2=6 years

and present time age of Raji=3+3=6 years

age of raju=6+3=9 years
