One year ago, the ratio of Laxman’s salary to Gopal’s salary was 3 : 5. The ratio of their individual salaries of last year to that of present year is 2: 3 and 4: 5 respectively. If their total salaries for the present year are 4,300, find the present salary of Laxman.

Correct option is A

​Given:

Laxman's salary to Gopal's salary 1 year ago = 3 : 5

Laxman's last year to present year = 2 : 3

Gopal's last year to present year = 4 : 5

Total current salaries = Rs. 4,300

Solution:

Let Laxman's salary last year = 3x and Gopal's = 5x.

Laxman's present salary = 3x × $$\frac{3}2$$​ = 4.5x.

Gopal's present salary = 5x × $$\frac{5}4$$​ = 6.25x.

Total present salaries = 4.5x + 6.25x = 10.75x = 4300.

=> x = $$\frac{4300} { 10.75}$$​ = 400.

So, Laxman's present salary = 4.5x = 4.5 × 400 = 1800.

Hence, Laxman's present salary is Rs. 1,800.
