Answer 2

Answer:

25

Step-by-step explanation:

First of all, we will find the number in order to know its 5/3rd

Let the number be x

x is multiplied by $\sf \dfrac{3}{5} \ of \ x$ to obtain 135.

∴,

$ \dashrightarrow \rm x \times \dfrac{3x}{5} = 135 $

$ \dashrightarrow \rm \dfrac{3x^2}{5} = 135 $

$ \dashrightarrow \rm x^2 = \dfrac{135 \times 5}{3} $

$ \dashrightarrow \rm x^2 = 45 \times 5 $

$ \dashrightarrow \rm x^2 = 225 $

$ \dashrightarrow \bf x = 15 $

Since we founded out the number, now we will find its 5/3rd

→ $ \dfrac{5}{3} \ of \ 15 $

→ $ \dfrac{5}{3} \times 15 $

$5 \times 5 = 25$

Hence, the number is 25.
