Preeti earned a total of $53 in interest last year. If the total amount of money in the accounts at the beginning of last year was $400, and there were no other deposits or withdrawals,
how much money was in account Y?

but i mnt geting the correct answer
ans :amounts in banks X and Y are 300 and 100 respectively.
