poorva x+6
dhruva x
3 years hence
x+6+3:x+3=4:3
x+9/x+3=4/3
cross multi.

Answer 2

Answer :

• Present age of Poorva = 27
• Present age of Durva = X = 21

Step by step explanation :

Hey Mate,

Present age of Poorva = X + 6

Present age of Durva = X

Before 3 years the Ratio of their age is 4 : 3

Before 3 Year Poorva age is = ( X + 6 ) - 3 = X + 3

Before 3 Year Durva age is = ( X ) - 3 = X - 3

∴  $\frac{X+3}{X-3}=\frac{4}{3}$

= > 3 ( X + 3 ) = 4 ( X - 3 )

= > 3X + 9 = 4X - 12

= > X = 21

Present age of Poorva = X + 6

= > 21 + 6

= > 27

Present age of Durva = X = 21
