2 belts and 3 ties cost rupees400. also 3 belts and 2 ties cost rupees 350. find the cost of a belt and a tie​

Answer 1

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
