Answer:
The above attachment shows answer of question no. 2
3. 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
The cost of each bat is Rs 500and the cost of each ball is Rs 50.
