The average monthly income of P and Q is Rs. 5,050. The average monthly income of Q and R is Rs. 6,250 and the average monthly income of P and R is Rs. 5,200. The monthly income of P is -

Explanation

The total monthly income of P and Q = 5,050 × 2 = Rs. 10,100 The total monthly income of Q and R = 6,250 × 2 = Rs. 12, 500 The total monthly income of P and R = 5,200 × 2 = Rs. 10, 400 ∴ The total monthly income of P, Q and R = $$ \frac{10,100 + 12,500 + 10,400}{2} $$ = $$ \frac{33,000}{2} $$ = Rs. 16,500 Therefore, P's monthly income = 16,500 – 12,500 = Rs. 4,000 (459) ## Page 8 ## Layout Attribution (Critical) A table of layout regions detected on this page is provided inside <layout_regions> tags.
