Verified answer

Answer:

Let the Age of Rabia be n yrs.

★ According to First Statement :

↠ Raza = Twice of Rabia

↠ Raza = 2 × n

↠ Raza = 2n — eq. ( I )

★ According to Second Statement :

↠ Kamran = 7 years younger than Raza

↠ Kamran = Raza – 7

• putting value of Raza from eq. ( I )

↠ Kamran = (2n – 7) — eq. ( II )

_____________________

☯ Sum of Ages :

⇴ Rabia + Raza + Kamran = 38

• putting value from eq. ( I ) & eq. ( II )

⇴ n + 2n + 2n – 7 = 38

⇴ 5n = 38 + 7

⇴ 5n = 45

• Dividing both term by 5

⇴ n = 9

━━━━━━━━━━━━━━━━━━━━━━

☯ RESPECTIVE AGES :

⟶ Rabia = n = 9 years

⟶ Raza = 2n = 2(9) = 18 years

⟶ Kamran = (2n – 7) = 2(9) – 7 = 11 years

∴ Age of Rabia, Raza & Kamran is 9 years, 18 years & 11 years respectively.
