Manas ordered 6 Levis jeans and some additional
Blackberry jeans. The price of one Levis jeans was twice that of one Blackberry jeans. When the order was executed it was found that the number of the two brands had been interchanged. This increased the bill by 40%. The ratio of the number of Levis jeans to the number of Blackberry jeans in the original order was?Solution
Let the number of Levis shirts ordered = x piece & Price of per Blackberry shirt = Rs 2a per unit Then, price of per Levis shirt = Rs a per unit According to the question, (6a + 2a x ) = (2a × 6 + a x ) × 140/100 30a + 10ax = 84a + 7ax Therefore, x = 18 Required answer = 6 : 18 = 1 : 3
