Question

One year ago the ratio between laxman and gopal salary was 3:4. the ratio of their individual salaries between last year's and this year's salaries are 4:5 and 2:3 respectively. at present the total of their salary is rs.4290. the salary of laxman now is :

Answer 1

Acc to question,

(4x + 2y)         3
-------------  =  ------
(5x + 3y)         4

solving it we can get x=y.

Also, acc to ques, 5x + 3y = 4290.  Since x=y; 5x + 3x = 4290 or, 8x = 4290 or, x = 536.25.

Now,

Laxman's past salary = 4 x 536.25 = 2145

Laxman's present salary = 5 x 536.25 = 2681.25

Gopal's past salary = 2 x 536.25 = 1072.5 

Gopal's present salary = 3 x 536.25 = 1608.75

Now you can tally the result.

Their tot present salary = 2681.25 + 1608.75 = 4290. [Proved]



 

Answer 2

1. Answer:

1650

Step-by-step explanation:

one year ago L/G = 3/4 ________________1

the present salary will be somewhat more than last year,

let it be L+L1 and gopal's be G+G1

individual salaries L/L+L1 = 4/5 __________2

                              G/G+G1 = 2/3 _________3

now eq. 2/3

$\frac{L/L+L1}{G/G+G1}$ = 4/5 x 3/2

L/G x (G+G1/L+L1) = 4/5 x 3/2

from 1

G+G1/L+L1 = 4/5 x 3/2 x 4/3

G+G1/L+L1 = 8/5

13 parts = 4290

1 part = 330

laxman salary 5 parts = 5 x 330

                                     = 1650
