Question

A number when increased by 40%becomes 42 .What is the number ​

Answer 1

Step-by-step explanation:

let say number is x,

according to the question,

40% of x + 42 = x

40x/100 + 42 = x

40x + 4200 = 100x

60x = 4200

x = 4200/60

x = 70

now verify the value of x

40*70/100 + 42 = 70

28 + 42 = 70

70 =70

so the number is 70
