Answer» Let the present age of the daughter be x years. Then, Present age of the WOMAN is 4X years. Five years hence, 4x+5 = 3(x+5) 4x + 5 = 3x + 15 4x - 3x = 15 - 5 x = 10 So the present age of the Daughter is 10 years.

22.

the age of a woman is four times the age of a daughter five years hence the age of the women will be three times the age of a Daughter the present ages of the daughter can you find that

Answer»

Let the present age of the daughter be x years.

Then, Present age of the WOMAN is 4X years.

Five years hence,

4x+5 = 3(x+5)

4x + 5 = 3x + 15

4x - 3x = 15 - 5

x = 10

So the present age of the Daughter is 10 years.

29.	Can someone help me out with this problem - Find 2 numbers such that their mean proportion is 24 and third proportion is 1536
Answer» Let the two NUMBERS be x and y. GIVEN that Mean PROPORTION of two numbers is 24. $= > \sqrt{xy} = 24$ *= > x y = 24 = > xy = 576 = > x = (576/y) ----- (1) Given that Third proportion is 1536. = > y^2 = x * 1536 ------ (2) Substitute (1) in (2), we get = > y^2 = (576/y) * 1536 = > y^3 = 576 * 1536 = > y^3 = 884736 = > y = 96. Substitute y = 96 in (1), we get = > x = (576/y) = > x = (576/96) = > x = 6. Therefore, the two numbers are 6 and 96. Hope this helps!**

29.

Can someone help me out with this problem - Find 2 numbers such that their mean proportion is 24 and third proportion is 1536

Answer»

Let the two NUMBERS be x and y.

GIVEN that Mean PROPORTION of two numbers is 24.

$= > \sqrt{xy} = 24$

= > x * y = 24

= > xy = 576

= > x = (576/y) ----- (1)

Given that Third proportion is 1536.

= > y^2 = x * 1536 ------ (2)

Substitute (1) in (2), we get

= > y^2 = (576/y) * 1536

= > y^3 = 576 * 1536

= > y^3 = 884736

= > y = 96.

Substitute y = 96 in (1), we get

= > x = (576/y)

= > x = (576/96)

= > x = 6.

Therefore, the two numbers are 6 and 96.

Hope this helps!
