Answers
Given : mr.pritesh got a job with an annual salary package of rs 4 lakh with 10% annual increment.
To Find : salary in the 5th year
total earning through salary in 10 years.
Solution:
Initial Salary = 4 lakh
Increment Rate = 10 %
Salary in 5th year = Salary after 4 Increment
A = P(1 + R1/00)ⁿ
=> A = 4 ( 1 + 10/100)⁴
=> A = 4 ( 1.1)⁴
=> A = 4 * 1.4641
=> A = 5.8564 lakh
salary in the 5th year = 5.8564 lakh
Salary 1 st year
4 , 4(1.1) , 4(1.1)² ...............................,4(1.1)⁹
Sum = a( rⁿ - 1)/(r - 1)
= 4 ( 1.1¹⁰ - 1)/( 1.1 - 1)
= 4(2.59374 - 1)/0.1
= 40 (1.59374)
= 63.7496 Lakh
