a fair price shopkeeper takes 10 % profit on his goods . he lost 40 % goods during theft . his loss percent is :
explanation : suppose he has 100 items . let c . p . of each item be re . 1 . total cost = rs . 100 . number of items left after theft = 60 . s . p . of each item = rs . 1.10 total sale = 1.10 * 60 = rs . 66 hence , loss % = 34 / 100 * 100 = 34 % answer : c
subtract(const_100, subtract(add(const_100, 10), divide(multiply(add(const_100, 10), 40), const_100)))
