- Salaries of Robert and Sam are in the ratio 2 : 3.
Question 1:
Salaries of Robert and Sam are in the ratio 2 : 3. If the salary of each is increased by Rs. 4000, the new ratio becomes 40 : 57. What is Sam's present salary?
A. 36000
B. 38000
Feedback Let the original salary of Robert and Sam be 2k and 3k respectively.
Then (2k+4000) / (3k+4000)=40/57
=> 57(2k+4000) = 40(3k+4000)
=> 114k + 2,28,000 = 120k + 1,60,000
=> 2,28,000 - 1,60,000 = 120k - 114k
=> 68000 = 6k
=> 3k = 34000
Sam's present salary = 3k+4000 = 34000 + 4000 = 38000
Then (2k+4000) / (3k+4000)=40/57
=> 57(2k+4000) = 40(3k+4000)
=> 114k + 2,28,000 = 120k + 1,60,000
=> 2,28,000 - 1,60,000 = 120k - 114k
=> 68000 = 6k
=> 3k = 34000
Sam's present salary = 3k+4000 = 34000 + 4000 = 38000
C. 34000
D. 39000
