Of the total amount received by a Bank Employee, 30% was spent on purchases and 10% of the remaining on transportation. If he is left with Rs. 630 after all mentioned expenditure, the amount (Rs.) received by him is:
1000
Let total amount received by him be X. So as per given condition,
X – 0.3 X – 0.07X = 630
X – 0.37X = 630
0.63X = 630
X = 1000
