Answer:
Tie = Rs 100
Belt = Rs 50
Step-by-step explanation:
Let Cost Of Belt =x
let cost of tie = y
According To Question :
2x + 3 y =400 (1)
3x + 2y = 350 ( 2)
Multiply eq 1 by 3 and eq 2 by 2
6x + 9y =1200 (3)
6x + 4y = 700 (4)
Subracting 4 from 3
5y = 500
y=100
Cost of tie = Rs100
From eq 1
2x + 3(100)=400
2x =400-300
2x =100
x=50
Cost of belt =Rs 50
