Question

From the salary of a worker, 10% is deducted as house rent, 15 % of the rest he spends on children's education and 10% of the balance he spends on cloths, after this expenditure, he is left with Rs 1377. His salary is ?

Answer 1

Let the salary be x,
Therefore,
For house rent=10%of x
For children's education= 15%of x
For clothes =10%of x
According to the question,
x-(10%ofx+10%ofx+15%ofx)= ₹1377
x-(10/100×x+10/100×x+15/100×x) =1377
x-7x/20=1377
23x/20= 1377
Therefore,
x=(1377×20)/23
x=₹1197.39
His salary is ₹1197.39.
