Question

Divide 34 in to two parts such a way that 4\7of one part is equal to 2/5of the other

Answer 1

let the first part be x and 2nd part becomes 34 - x  --------------- (i)
Given, 4 upon 7 is equal to 2 upon 5, it can be written as
4/7(x ) = (34 - x )(2/5) 
4x/7 + 2x/5 = 34 x 2/5 = 68/5 
4x/7 = 68 - 2x/5
20x = 476 -14x
34x = 476
x = 476/34
x = 14.
on substituting x in equation (i) we get
= 34 - 14 
= 20

Two parts are 14 and 20.


Hope this helps!

Answer 2

HELLO.......FRIEND!!

THE ANSWER IS HERE,

Let the first part contains x . Then the other part contains 34-x.

From the question,

$= > \: \frac{4}{7} (x) = \frac{2}{5} (34 - x)$

$= > \: \frac{4x}{7} \times \frac{5}{2} =34 - x$

$= > \: \frac{10x}{7} = 34 - x$

$= > \: x + \frac{10x}{7} = 34$

$= > \: \frac{17x}{7} = 34$

$= > \: x = 14$

So, The first part contains 14 & other part contains 20.
