Q10. 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. 5200. The monthly income of P is:
(a) Rs. 3,500
(b) Rs. 4,000
(c) Rs. 4,050
(d) Rs. 5,000
Answers
3. Ans.(c)
Sol. Sum of internal angle = 1440
180(n – 2) = 1440
n – 2 = 1440/180
n = 8 + 2 = 10
Ans.(b)
Sol. Sum of P and Q = 5050 × 2 = 10100
Sum of Q + R = 6250 × 2 = 12500
Sum of P + R = 5200 × 2 = 10400
(P + Q + R) = 33000/2=16500
Monthly income of P = 16500 – 12500 = 4000
(a) 990 km
(b) 1200 km
(c) 1320 km
(d) 1440 km
