Plz help me.
Question number 10.

Answer 1

SAY ,Aman = A

SON = S

According to question

A = 3S -----(i)

10 YEARS AGO,

(A- 10) = 5(S-10)

FROM (i)

3S - 10 = 5S - 50
2S = 40

S = 20 years

A = 3S = 3×20 = 60 Years


Present Age of father = 60

Present age of son = 20


Hope it helps

Answer 2

let the present age of son be = X years

therefore Amans present age =3X years
ten years ago sons age = (X-10)
amans age =3X-10

according to the condition we have
songs age ( 10 years ago ) ×5= Amans age (10 years ago)

or. (X-10) ×5= (3X-10)
or. 5x-50=3x-10
transposing (-50) to RHS and 3x to LHS ,we have
5x-3x=(-10)+50
2x=40
x=40/2
x= 20
dividing both sides by 2
3x= 3×20
sons present age =20
Amans present age=60
