Let X be the initial salary .
15% of X = 15/100 × X = 15X/100
According to the question,
X + 15X/100 = 9936
100X + 15X = 9936 × 100
115X = 993600
X = (993600/115 )
X = 8640.
Hence,
Initial salary of a person = x = 8640.
15% of X = 15/100 × X = 15X/100
According to the question,
X + 15X/100 = 9936
100X + 15X = 9936 × 100
115X = 993600
X = (993600/115 )
X = 8640.
Hence,
Initial salary of a person = x = 8640.
