Answer 1

Answer:

9 marbles

Step-by-step explanation:

Let the no. of marbles Ravi has be x

x + 2x = 27

3x = 27

x = 27/3

x = 9

Answer 2

Answer:

9

Step-by-step explanation:

Let the number of marbles he initially had be x

Now he received from his friend Kavya twice the marbles that he had i.e 2x. Now he has 27 marbles.

Therefore,

final number of marbles with him = initial number of marbles that he had + the number of marbles he was given to. i.e.

$x + 2x = 27$

$or \: 3x = 27$

$or \: x = 9$

Therefore,

initial number of marbles he had => x = 9
