A market woman sells oil in cylindrical tins 10cm deep and 6cm in diameter at N15.00 each. If she bought a full cylindrical jug 18cm deep and 10cm in diameter for N50.00, how much did she make by selling all the oil?

Correct Answer: Option D

Explanation

V(pi)r²h = (pi)(3)²(10) = 90(pi)cm³
V = (pi)(5)² x 18 = 450(pi)cm³
No of volume = (frac{450pi}{90pi})
= 5
selling price = 5 x N15 = N75
profit = N75 – N50 = N25.00
