Question

som is 3 years younger than raj. after five years the sum of their ages would be 31. find their present ages.

Answer 1

Answer:

raj age will be 12 and som age will be 9

Step-by-step explanation:

let the age 9f raj be =x

[x+5] + [x-3+5] =31

2x -3+10 =31

2x -3 = 31 -10

2x -3 =21

2x =21 +3

2x =24

x =24/2

x = 12

so here x is 12 so raj =x

rai 12

som = x -3

so 12 -3 =9

so raj =12 and som =9

Answer 2

Step-by-step explanation:

let raj be x

and som be x-3

after 5 years, raj= x+5

som= x-3+5 = x+2

hence,

(x+5) (x+2) = 31

or 2x + 7 = 31

or 2x = 24 i.e. x = 12

therefore, present ages of raj = 12 and som = 12 - 3 = 9.
