Virat.
A) 3000
B) 4000
C) 5000
D) 6000​

Answer 1

Answer:

salary of Virat is ₹6000

Step-by-step explanation:

let us assume that salary of Virat &Yusuf be x & y resptly.,

given that the expense % of Virat is 70%,

=> savings % of Virat is 30%

similarly savings % of Yusuf is 25%  

so we have x + y = 18000

and also 30/100 * x : 25/100 * y = 3:5

=> [ 3/10 *x ] / [1/4 * y] = 3/5

=> [ 3/10 *x ] * 4/y = 3/5

=> 2x / y = 1

=> y = 2x  (or)  x = y/2

=> x = (18000-x)/2

=> 2x = 18000 -x

=> 3x= 18000

=> x = 6000

Hence salary of Virat is ₹6000
