Answer:
Step-by-step explanation:
Given:
Current salary= 19800
1st year increase 20%
2nd increase 10%
We have to find salary two years ago
let x be the salary two years ago.
salary after 1st year increase @ 20% = x + x * 20/100= 120x / 100=6x / 5
salary after 2nd year increase @ 10% that is current salary= 6x/5 + 6x / 5* (10/100) =>6x/5+ 6x/5* 1/10 =19800
6x / 5 + 6x / 50 = 66x / 50 = 66x / 50=19800
so 66x/50 = 19800 = > x = 19800 /66 * 50 = 15000
salary two years ago was 15000
