imran gives 1% of his monthaly income to his two son as pocket money. The elder son gets 80% of his share. If he saves Rs.60 per month, determine Imran's monthly income.
Let monthly income be x
Total money given out = 100x
elder son gets = 10020×100x=500x
elder son spends - 20%
elder son saves - 80%
⇒10080×500x=5×1258=20
x⇒12,500
