Answer:
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.
