Ek Dada,
Ek Bap,
Ek Pota,
Tino ki age 140 yers.
Pota jitne month ka dada utne sal ka,
pota jitne din Ka,.Bap utne week ka,
WHAT IS THE SOLUTION?
OK here it is.
Dada is 84 years old (grandfather)
Baap is 49 years old (father)
Pota is 7 years old (grandson)
Check: 84 + 49 + 7 = 140 years
Read below if you want to know how to solve (Its a simultaneous eq. of 3 variables bdw :)):
Let Dada be D years, Baap be B years and Pota be P years
D + B + P = 140 (given)----------------------------- (1)
Constraints:
D = 12P; --------------------------------------------------- (2) 1 year is 12 months; 52 weeks; and 365 days
52B = 365P; --------------------------------------------- (3)
Substitute value of P from (3) into (2) therefore D = (12 * 52/365)B ------------------- (4)
Put (4) in 1 to get
(12*52/365)B + B + (52/365)B = 140
This gives B = 49 years. Put in above eqs to get other values.
