   A’s monthly salary = Rs. P
   ∴ B’s monthly salary = Rs. (40000 – P)
   A spends 85% of his income.
   

   ∴ A’s savings =	15P	= Rs.	3P
   	100		20

   
   

   B’s savings = (40000 – P) ×	5
   	100

   
   

   = Rs.			40000 - P
   			20

   
   

   Correct Option: A

   A’s monthly salary = Rs. P
   ∴ B’s monthly salary = Rs. (40000 – P)
   A spends 85% of his income.
   

   ∴ A’s savings =	15P	= Rs.	3P
   	100		20

   
   

   B’s savings = (40000 – P) ×	5
   	100

   
   

   = Rs.			40000 - P
   			20

   
   

   ∴	3P	=	40000 - P
   	20		20

   
   ⇒ 3P = 40000 – P
   ⇒ 4P = 40000
   

   ⇒ P =	40000	= Rs. 10000
