Step-by-step explanation:
Let the cost of one Bat be x
and the cost of one ball be y
Then According to Question
7x+6y=3800 ---(i)
3x+5y=1750 ---(ii)
multiplying (i) by 3 and (ii) by 7 we get
21x+18y=11400 (iii)
21x+35y=12250 (iv)
subtracting (iv) from (iii) we get
−17y=−850
⇒y=50
putting y=50 in (i)
7x+6y=3800
⇒7x+6×50=3800
⇒7x=3800−300
⇒x=500
Therefore the cost of each bat is Rs 500
and the cost of each ball is Rs 50
