Answer 1

Answer:

old salary = 12350

Step-by-step explanation:

let  his  salary before the increase be y

10/100 x y= y/10

old salary + increased salary = new salary

y + y/10=13585

10y/10+y/10=13585

11y/10=13585

11y=135850

therefore y= 13585/11=12350

Answer 2

AnswEr :

• Let Amit’s Salary before Increase be Rs. x
• Increase = 10%
• New Salary = Rs. 13585

• Let's Head to the Question Now :

$:\implies\sf Old\:Salary \times (100 + Increase)\% = New \:Salary\\\\\\:\implies\sf Rs. x \times (100 + 10)\% = Rs. 13585\\\\\\:\implies\sf Rs. x \times 110\% = Rs. 13585\\\\\\:\implies\sf x \times\dfrac{110}{100} = 13585\\\\\\:\implies\sf x = \cancel\dfrac{13585 \times 100}{110}\\\\\\:\implies \boxed{\sf x =Rs.\:12350}$

⠀

∴ Hence, Amit Old Salary was Rs. 12350.
