John purchased some shirts and trousers for $1550. He paid $250 less for the shirts than he did for the trousers. If he bought 5 shirts and the cost of a shirt is $20 less than that of a trouser, how many trousers did he buy? | [
"7",
"4",
"5",
"6"
] | D | Given that the total purchase of two items cost 1550.
So the average purchase of one item will cost 1550/2 =775.
Its given as total shirt cost 250$ less. Hence Total Shirt cost = 775 - 125 and Total trouser cost = 775 + 125
5 shirts =650$ ==> One shirt =130$
One trouser = 130 + 20 =150$
Total trousers = 900 / 150 =6.

Formula n(a∪b) = n(a) + n(b) − n(a∩b)
Fail in Hindi or English = 30 + 42 – 28 = 44
Therefore students who passed = 100 – 44 = 56.
