Question

sam,ravi and Elliot have 92 marbles altogether.
sam has 3 times as many marbles as Ravi.
Ravi has 2 Fewer Marbles than Elliot.
how many marbles does Ravi have?

Answer 1

let the number of marbles Ravi has be : x
Ravi : x marbles
Sam : 3x marbles
Elliot: x + 2
x + 3x + (x + 2) = 92
5x + 2 = 92
5x = 92-2= 90
x= 90/5 = 18
The answer is 18.
