When net salary is 10350 and 13.75% pf deducted how gross amount is calculated..
For eg: If gross salary is 12000, pf is 13.75% then
net salary= 12000* 13.75% = 10350 But how to calculate reverse way wen we know net salary as 10350 and pf deduction as 13.75% using simple formula
Hint
Let us call $N$ the net salary, $G$ the gross salary and $x$ the percentage corresponding to the pf deduction. So, you have $$N=G\times (1-\frac{x}{100})$$ This gives you the relation between the three quantities. From this, you can extract $G$ and get $$G=\frac{100 N}{100-x}$$
