Answer 1

Answer:

60

Step-by-step explanation:

let the numbe be x

x +40/100x = 84

100x/100 +40x/100 =  84

140x=8400

x=8400/140

x=60

Answer 2

Answer:

The number is 60.

Step-by-step explanation:

Let's assume that, the number is x

According to the problem:

$x + \frac{40}{100} x = 84$

$=>x + 0.4x = 84$

$=>10x + 4x = 840$  [multiplying by 10]

$=>14x = 840$

$=>x = \frac{840}{14} = 60$
