Answer 1

Answer:

1.let the first no=x

another no=4\5×x=4x/5

the sum of both no =70

Atq,

x+4x/5=70

=9x+5/5=70

=9x+5=350

=9x=350-5

=9x=345

=x=345/9

=x=35

Answer 2

Answer: Let a no.be x

Another no. be y

x=4y/5

Sum of them are 70

means: x+y=70

4y/5+y= 70

9y/5= 70

y = 70×5/9= 350/9

value of x= 3/5×350/9

70/3 i.e. 23 whole 1/3
