Naresh’s monthly income is 30% more than that of Raghu. Raghu’s monthly income is 20% less than that of Vishal. If the difference between the monthly incomes of Naresh and Vishal is 800, what is the monthly income of Raghu?	Answers:  A) 16,000  B) 20,000  C) 12,000  D) Data inadequate  E) None of these
N = R + 30% of R = 1.3 RR   = V – 20% of V = 80% of V = 0.8 V   ∴ N = 1.3 × 0.8V = 1.04 V   Now, N – V = 1.04 V – V = 0.04 V = 800(given)   ∴ V = 20000   ∴ R = 0.8 × 20000 = 16000   16,000nswer 16,000
