The ratio between Sonia and Priya age at present is 4 : 5 .  Sonia is 7 years younger than Priya .  The ratio of Sonia's age to Priya's age after 6 years will be?

34 : 41 

Let Present age of Sonia and Priya = 4R &  5R

ATQ,

Difference of age ⇒ 1R = 7 years

Therefore,

Present age of Sonia = 4 × 7 = 28 years

Present age of Priya = 5 × 7 = 35 years

After 6 years ratio of age will be = (28 + 6) : (35 + 6)

                                                      = 34  :  41
