When a qns give 2 sets of similar items in different quantity.. U need to at least get one of the item to be of the same quantity in order to compare the item that remained different as the price difference will be for that item..
Convert t shirt into the same quantity.. By multiplying this set by 2.. So 6caps n 4 tshirts cost 25.. Whereby the other set is t caps n 4 tshirt 22.70.. This mean the additional cap cost 2.30 since bothe have same amt of tshirt.. So the only variable is cap

Reason why we dun convert the cap becos the first common multiple for 5 and 3 is 15 while 2 and 4 is 4 so its easier if u convert tshirt instead of cap..
