Question

What number increased by 30% equals 260

Answer 1

The number is 200

Explanation:

Let the number to b "x"

Given condition says:

x + 30%(x) = 260

As 30% can be written as: 0.3 So equation becomes:

x + 0.3 x = 260

Adding terms having variable x

1.3 x = 260

Dividing both sides by 1.3 we get

1.3/1.3 x = 260/1.3

x = 200

Proof:

Putting x = 200 in equation: x + 0.3 x = 260

200 + 0.3(200) = 260

200 + 60 = 260

260 =260

Hence proved.
