Ravi and Arjun have 30 and 70 marbles respectively.
Given,
The ratio of marble available with Ravi and Arjun = 3:7
The total marbles = 100
To Find,
The number of marble with both of them =?
Solution,
Let x be a number such that
The number of marbles Ravi has = 3x
The number of marbles Arjun has = 7x
The sum of these marbles = 100
3x + 7x = 100
10x = 100
x = 100 / 10
x = 10
The number of marbles Ravi has = 3x = 3 x 10 = 30
The number of marbles Arjun has = 7x = 7 x 10 = 70
Hence, the number of marble with Ravi and Arjun have are 30 and 70 respectively.
