Luna used 3/5 of her money to buy 4 wallets and 4 earphones. The cost of 2 wallets was the same as that of 3 earphones. What was the most number of earphones Luna could buy with the rest of her money?

Luna used 3/5 of her money to buy 10 earphones.

Rest of the money is (1 - 3/5) = 2/5.
Let, Luna buy x earphones with the

rest of her ,only.

So, 10/3/5 = x/2/5

=> 50/3 = 5x/2

=> x = 29/3 = 6

So, Luna can buy almost 6 earphones with the rest of her money.
