Question

divide 34 into 2 parts in such a way that 4/7 of one part is equal to 2/5 of the other​

Answer 1

Answer:

let the two parts be x and y .

then given is

x + y = 34 - (1)

Also

4/7 × x = 2/5 × y

By solving it comes

20x - 14y = 0 - (2)

Multiplying 20 to equation 1

20x + 20y = 680 - (3)

Now by subtracting 2 from 3

34y = 680

y = 20

Put y in equation 1

x + y = 34

x + 20 =34

x = 14
