Answer

let age of Arjun be

′

x

′

and age of Shriya be

′

y

′

then according to question x=2y−−−(1)

and five years ago

x−5=3(y−5)

x−5=3y−15

x−3y+10=0−−−(2)

using eq(1)

2y−3y+10=0

y=10

and x=20

∴ age of Arjun is 20 and age of Shriya is 10

Answer 2

Answer:

Hope it helps

Step-by-step explanation:

Let 2 years ago age of daughter be x and that of Ritu is 3x

After 2 years age of daughter will be (x + 4) years and That of ritu will be (3x + 4) years

According to the question

2(3x + 4) = 5(x + 4)

⇒ 6x + 8 = 5x + 20

⇒ x = 12

Present age of daughter = x + 2

Present age of Ritu = 3x + 2

Required sum = x + 2 + 3x + 2 = 4x + 4 = 4 × 12 + 4 = 52
