Answer:
36 %
Step-by-step explanation:
Let Imran's present salary be x
Decrease in 20 % = x - 20% of x
= x - 20/100 x
= 100x/100 - 20x/100
= 80x/100
Another 20 % Decrease = 80x/100 - 20% of 80x/100
= 80x/100 - 20/100 (80x/100)
= 80x/100 - 1600x/10000
= 80x/100 - 16x/100
= 64x/100
= 64/100 (x)
= 64 % of x
Present salary = x = 100% of x
Percentage Decrease (or) Percentage loss = 100 - 64 = 36 %
