Emily ages is 2/9 of her father age. In 6 years time, their total age will be 78 years. Find the ratio of Emily's age to her father age in 6 year time

a. 2:9
b. 8:15
c. 3:10
d. 5:13

C. 3 : 10

Penjelasan dengan langkah-langkah:

E = Emily

F = father

E : F = 2 : 9

E + 6 + F + 6 = 78

E + F = 78 - 6 - 6

= 66

E = 2/11 x 66 = 12

F = 9/11 x 66 = 54

(E+6) : (F+6) = (12 + 6) : (54 + 6)

= 18 : 60

= 3 : 10
