Question

A number increase by 20 percent give 42 .the no is?​

Answer 1

Answer:

Number is 35.

Step-by-step explanation:

Let the number be x.

x + (x×20/100) = 42

x + 20x/100 = 42

(100x + 20x)/100 = 42

120x/100 = 42

120x = 42 × 100

120x = 4200

x = 4200/120

x = 420/12

x = 35

Number is 35.
