Question

A number increased by 20% gives42 the number is

Answer 1

Step-by-step explanation:

Let the number be x

x increased by 20% = 42

20% of x =

20 ÷ 100 × x

20x ÷ 100

----------------------------------------------------

x + 20x ÷ 100 = 42

100x + 20x ÷ 100 = 42

120x ÷ 100 = 42

x = 42 × 100 ÷ 120

x = 35

----------------------------------------------------

20% of 35 =

20 ÷ 100 × 35

7

35 + 7 = 42

----------------------------------------------------

35 increased by 20% gives 42.
