Question

13. Subodh is 10 years older than Amogh. After 10 years their total age will be
40 years. What is Subodh's age today?
(1) 15 years
(4) 30 years.
(2) 20 years
(3) 24 years​

Answer 1

let age of amogh= a years

age of subodh = 10 years older than amogh

= a + 10

after 10 years

their ages are a+10, a+20

their total age will be 40 years

a+ 10+a+20= 40

2a + 30 = 40

2a = 40-30

2a = 10

a = 10/2

a= 5 years

a+10

= 5+10

=15 years

so

so age of Amogh = a = 5 years

so age of Amogh = a = 5 yearsage of Subodh= a+ 10= 5+10= 15years

Answer 2

Answer:

let the amogh age be x

and subodh age will be (x+10)

after ten years the sum of their ages is 40 years

then,

the sum of their ages after 10 years will be

x+(x+10)=40

2x+10=40

2x=40-10

2x=30

x=30/2

x=15

their ages

amogh's age after 10 years=x

=15years

amogh's present age will be= 15-10

=5years

subodh's age after 10 years=x+10

=15+10

=25years

subodh's present age will be=25-10

=15years

ANS= 15 years
