Let the number is X,

A/Q

5 + X/3 = 25

X/3 = 25 - 5

X/3 = 20

X = 20 ✖ 3

X = 60

Hence, required number is 60 ( ANS )

Answer 2

Answer:

45

Step-by-step explanation:

Let the number be x

According to the question,$\frac{x}{5} + \frac{x}{3} + \frac{x}{9} = 29$

L.C.M of 5,3,9 is 45.

Then the equation becomes:

$\frac{x \times 9}{5 \times 9} + \frac{x \times 15}{3 \times 15} + \frac{x + 5}{9 + 5} = 29$

$⟹ \frac{9x+15x + 5x}{45} = 29$

$⟹x= \frac{29 + 45}{29}$

∴ x=45
