Answer 1

Answer:

let the no. ne x

x+ 35% of x = 189

x + 35/100 * x = 189

100x + 35x/100 = 189

135x / 100 = 189

x = 189 * 100/135

x = 189 * 20/27

x = 7 * 20

x = 140

The no. is 140.

Answer 2

Answer:

The number is 140

Step-by-step explanation:

Suppose the unknown number is x,

After increasing 35%,

New number = x + 35% of x,

$=x+\frac{35x}{100}$

= x + 0.35x

= 1.35x

According to the question,

$1.35x = 189$

$\implies x =\frac{189}{1.35}= 140$

Hence, the required number is 140.
