Since average age of all three persons is 22;
∴ S + A + J = 66 ---- (1)
∵ The present age of Sumit is 1/7th of the present age of Ashok;
∴ S = A/7 ---- (2)
And the age of Ashok will be twice the age of Jitendra after 6 years;
∴ A + 6 = 2(J + 6)
⇒ J = [(A + 6)/2] - 6 ---- (3)
From equation (1), (2) and (3)
⇒ A/7 + A + [(A + 6)/2] - 6 = 66
⇒ [2A + 14A + 7A + 42 - 84]/14 = 66
⇒ 23A = 924 + 84 - 42 = 966
⇒ A = 42
∴ J = [(42 + 6)/2] - 6 = 18
∴ Present age of Jitendra = 18 years
∴ S + A + J = 66 ---- (1)
∵ The present age of Sumit is 1/7th of the present age of Ashok;
∴ S = A/7 ---- (2)
And the age of Ashok will be twice the age of Jitendra after 6 years;
∴ A + 6 = 2(J + 6)
⇒ J = [(A + 6)/2] - 6 ---- (3)
From equation (1), (2) and (3)
⇒ A/7 + A + [(A + 6)/2] - 6 = 66
⇒ [2A + 14A + 7A + 42 - 84]/14 = 66
⇒ 23A = 924 + 84 - 42 = 966
⇒ A = 42
∴ J = [(42 + 6)/2] - 6 = 18
∴ Present age of Jitendra = 18 years
