Question

Ashish got 20% raise in the salary if his new salary is 156000 then find his original salary ​

Answer 1

let us use direct proportion method

if his salary before raise was ₹100 then after raise It'll be ₹120

(as raise was 20%, 20/100 * 100, 100 and 100 gets cancelled so raise is ₹20)

before raise after raise

100 120

x 156000

(by cross multiplication)

120x = 156000*100

120x = 15600000

x 15600000/120

x = 130000

hope it helps

have a great day

Answer 2

Answer:

Step-by-step explanation:

Let say Original Salary of Ashish =   X  Rs

Raise = 20 %

20% Raise  = (20/100)X  = 0.2X  Rs

New Salary = Original Salary + Raise

=> New Salary = X + 0.2X   Rs

=>  New Salary = 1.2X   Rs

New Salary =  156000  Rs

Equate New Salary

1.2X =  156000  

=> X = 130000 Rs

original salary  = 130000 Rs
