Does anyone know how to do this question?
20 men take 16 days to build a 80m tunnel. After working for 4 days, 4 men came down with dengue fever. Find the number of days the remaining men need to work in order to complete the building of the tunnel.
This question is from the second MYE revision Maths Paper Miss Tan gave. This is a Sec 2 topic question under Proportion. I am not sure whether will it be tested tomorrow or the day after. But it is better to be safe than sorry.
This is also from the same paper... Given that -3 and 1/2 are the roots of a quadratic equation, form the quadratic equation.
Also from the same paper... Paper 1 Question 14... Two containers shown in the diagram are geometrically similar. The height of the smaller container is 10 cm and the height of the larger container is 15 cm.......... cont on Paper 1 Question 14 page 15
