Question

7. A certain sum is distributed among X, Y and Z. X and Y together got Rs.7,400, Y and Z got Rs.9,500
and Z and X together got Rs.8,500. What is the share of Y?
a) Rs.3,200
b) Rs.4,200
c) Rs.5,300
d) Rs.6,300​

Answer 1

Rs.4,200

Step-by-step explanation:

(X+Y)+(Y+Z)+(Z+X)=7400+9500+8500

2X+2Y+2Z =25400

X+Y+Z =12700 (dividing both sides by 2)

Y =12700-(X+Y)

Y =12700-8500

Y =4200
