Question

Rajesh bought 10 balls and 10 bats for rupees 2800 if each bat cost three times a ball does then what is the price of a bat?​

Answer 1

Answer:

Price of a bat is Rs210.

Step-by-step explanation:

Let the cost of a bat be Rs x and that of ball be Rs y.

As per question,

10x + 10y = 2800

x = 3y

Substituting value of x

10(3y) + 10y = 2800

40y = 2800

y = 70

So, x = 3y

x = 3(70)

x = 210

The cost of a bat is Rs210

The cost of a ball is Rs70

Answer 2

Step-by-step explanation:

given condition is

cost of bat =3[cost of ball]

1ball +1bat=280

3bat+1bat =280

.4bat=280

1bat=70

the cost of one bat is 70rupees
