Step-by-step explanation:

Requirednumber=50

Step-by-step explanation:

Let \: the \: number = xLetthenumber=x

\begin{gathered}\frac{2}{5} \: times \: of \: the \: number \\= \frac{2x}{5}\end{gathered}

5

2

timesofthenumber

=

5

2x

/* According to the problem given, we get

Sum \: of \: the \: number = 70Sumofthenumber=70

\implies x + \frac{2x}{5} = 70⟹x+

5

2x

=70

\implies \frac{5x+2x}{5} = 70⟹

5

5x+2x

=70

\implies \frac{7x}{5} = 70⟹

5

7x

=70

\implies 7x = 70 \times 5⟹7x=70×5

\implies x = \frac{70\times 5}{7}⟹x=

7

70×5

\implies x = 10 \times 5⟹x=10×5

\implies x = 50⟹x=50

Therefore,

Required \: number = 50Requirednumber=50

Answer:

Let the first number = x

and second number is two fifth times so number = 2/5x

given that the sum = 70

2/5x + x = 70

7/5x = 70

x = 350/7

x = 50

50 is your answer so number which is required we find as 50
