Sundaram joined a company for a fixed salary per month. After few months, the management felt happy with his work and multiplied his salary by some n times. This happened every few months and his salary kept getting multiplied and he reached a salary of 360 zeds. Every time the management increased the salary by a prime number of times only and his initial salary was 5 zeds.

Question: 1. How many times management did give incentive to Sundaram?
2. What is the maximum increment he got in his salary?
3. What is the least incentive he got? What would be his salary had he got the same type of increment every time?
4. Had his first salary been 9 zeds what would be his present Salary?

what, still unclear?

1. 360 = 5 * 2^3 * 3^2
So, he got 5 raises: 2,2,2,3,3 times
2. 3 times. before the last raise (of 3 times), his salary was 5*8*3 = 120
so, his raise was another 240, making his final salary of 360
3. 5 (5*2 = 10, 5 more than his starting salary) 5*2^5 = 160
4. well, it would be 9/5 as much, right?

thank u sir.

all rong

How many times management did give the incentive to Sundaram

a. 3
b. 5
c. 4
d. 6

thank u

Answer : many of you think that how we solve this . So we know his initial salary is 5 zeds and final salary is 360 . And it increases by n (prime no.) By fundamental theorem we find the prime factors of 360 =222*335
