Question

Some marbles in a bag are red and the rest are blue. If one red marble is removed,

then one-‐seventh of the remaining marbles are red. If two blue marbles are

removed instead of one red, then one fifth of the remaining marbles are red. How

many marbles were in the bag originally?​

Answer 1

Answer:

I think 47 marbles are there

Answer 2

Answer:

22

Step-by-step explanation:

let, there are y marbles. And among them x are red.

so,rest are (y-x) [blue]

#(x-1)=(y-1)/7 --------> 7x -y=6

## x=(y-2)/5 --------> 5x-y=(-2)

after solving those eqn.

x=4,y=22

therefore the total number of marbles in the bag is

22
