The new shirt will cost X Rs. 418.40
Let the pocket money be Rs a.
Therefore, 15% of a+ 85% of a = a.
Now, 85% of a = 1360 + 20% of a (As X spends 20% of the remaining amount in buying shirt and the remaining amount is 85% of total pocket money 'a').
After solving each of them, we get a's value and then the new shirt's value.
Thank you.
