E) rs . 4200

Rationale: let the income of p 1 and p 2 be rs . 5 x and rs . 4 x respectively and let their expenditures be rs . 3 y and 2 y respectively . then , 5 x – 3 y = 1600 … ( i ) and 4 x – 2 y = 1600 … … . . ( ii ) on multiplying ( i ) by 2 , ( ii ) by 3 and subtracting , we get : 2 x = 1600 - > x = 800 p 1 ’ s income = rs 5 * 800 = rs . 4000 answer : c
