Let the number be x × 4/7 & x × 2/5
According to question..
X × 4/7 = 34 - X × 2/5
4x/7 = 34/1 - 2x/5
4x/7 = 170 - 2x/5
4x × 5 = (170 - 2x) 7
20x = 1190 - 4x
20x + 14x = 1190
x = 1190/34
x = 35
So,
The numbers are
❇️ x ×4/7 = 20
❇️x × 2/5 = 14

Answer
let us assume one number be x and another be 34-x.
Now we have according to the question=>
4/7(x) = 2/5(34-x)
=>4x/7 = (68 -2x)/5
=>20x = 476 - 14x
=>34x = 476
=>14.
Hence the numbers are 14 and 20. respectively.
Verification
1)Sum of two numbers = 34
Lhs
=>14 + 20
=>34
Rhs
=>34
Since Lhs=Rhs
hence it is correct.
2)Also given=>
4/7(x) = 2/5(34-x)
Lhs
4/7×(14)
=>8
Rhs
2/5×(20)
=>8
So again Lhs = Rhs.
hence proved.
