The ratio of the present ages of Sunita and Vinita is 4 : 5. 6 yr hence, the ratio of their ages will be 14 : 17. What will be the ratio of their ages 12 yr hence?

15 : 19

Present age of Sunita = 4x
Present age of Vinita = 5x
6 yr hence, $fraction numerator 4 straight x plus 6 over denominator 5 straight x plus 6 end fraction equals space 14 over 17$
$rightwards double arrow space space 68 straight x plus 102 space equals space 70 straight x plus 84 rightwards double arrow space space 68 straight x minus 70 straight x space equals space 84 minus 102 rightwards double arrow space minus 2 straight x space equals space minus 18 rightwards double arrow space space space space space straight x space equals space 18 over 2 space rightwards double arrow space space straight x space equals space 9$
So, Present age of Sunita
= 4 x 9 = 36 yr
Present age of Vinita = 5 x 9 = 45 yr
12 yr, hence $fraction numerator 36 plus 12 over denominator 45 plus 12 end fraction equals space 48 over 57$
Required ratio = 16 : 19
