One-fifth of a number is equal to $$\dfrac{5}{8}th$$ of another number. If 35 is added to the first number, it becomes four times of the second number. Find the second number.
Let us assume the first number is A and the second number is B.
One-fifth of a number is equal to $$\dfrac{5}{8}th$$ of another number.
$$\dfrac{A}{5}=\dfrac{5B}{8}$$
=> $$A=\dfrac{25B}{8}$$ -----(1)
Also, if 35 is added to the first number, it becomes four times the second number.
$$A+35=4B$$ .......(2)
Substituting the value of (1) in (2)
$$\dfrac{25B}{8}+35=4B$$
$$\dfrac{7B}{8}=35$$
B = 40
