Question

Find the number which when increased by 30% becomes 39nd the number which when increased by 30% becomes 39.

Answer 1

The original number + 30% of the original number = 39
130% of original number = 39
100% of the original number = (39*100)/130 = 30.

Answer 2

let it be X
X + 30% of X = 39
X+0.3X = 39
1.3X = 39
X = 39/1.3 = 30

so the number is 30
