WASSCE 2025 CORE MATHEMATICS TRY QUESTIONS 1. a) Without using tables or calculator, evaluate 3√7(7-2√7), if √7 = 2.646 b) The cost of producing a motor car in a certain factory is partly constant and partly varies inversely as a number of cars produced per day. If the cost of producing each car is 1,600 dollars when 4 cars are produced per day and 1,420 dollars when 5 cars are produced per day, find the rate of production necessary to bring the cost down to 1,150 dollars per cars 2. If 3m x 3n = 243 and 3m ÷ 32n = 9, write down two Hence equations connecting m and n. find the values of m and n. 3. a) The cost of a packet of sugar is x cedis and the cost of a tin of milk is y cedis. If 3 packets of sugar and 4 tins of milk cost ¢635.00 and 4 packets of sugar and 3 tins of milk cost é695.00, write two equations connecting x and y. Hence find x and y. 0542743763 b) The cost of production of a wireless set was ₵40,000.00. The manufacturer sold it to a wholesaler at a profit of 20 per cent. The wholesaler also sold it to a retailer at a profit of 25 per cent. The retailer marked the set to be sold at a price 50 per cent above what he paid for it. i) Find the marked price ii) To a customer who paid cash, the retailer reduced the price to ₵75,000.00.
