Answer:
30 months
Step-by-step explanation:
Taking every data monthly
Priya earning for first month = Rs 15000
Priya Expenses for 1st month = Rs 13000
Priya Saving for 1 st month = 15000 - 13000 = Rs 2000
Salary increased in subsequent month = Rs 1500
Expenses increased in subsequent month = Rs 900
Saving increased in Subsequent month = 1500 - 900 = Rs 600
Saving for first month = a = rs 2000
Saving increased in subsequent month = d = Rs 600
Saving in nth Month = a + (n-1)d
= 2000 + (n-1)* 600
= 2000 + 600n - 600
= 600n + 1400
600n + 1400 = 20000
=> 600n = 18600
=> n = 31
31st months her saving would b Rs 20000 per month
so it will take 30 months
