PROBLEMS
Boys and Girls Four boys and three girls are seated in a row. What are the chances that the two children at the ends of the row will be girls? -(Problem from R.C.J.M.). Tom’s Watch Tom bought a cheap watch. He found that it kept better time if he wound it twice a day. He wound it with eight turns at 7.30 am., and with twelve turns as he went to bed. At what time did he go to bed? -(Problem from Rob, Ahipara). Clock At which times between four and five o'clock are the hands of a watch separated by a 20-minute space? -(Problem from A.G.T., Picton). Race Problem A is for Aryan, who runs faster than B, an ordinary Bloke. He runs 1 1/19
faster, in fact. He runs a race with C, for just a Common Cuss, and beats C, naturally, by 8 4/5 yards in 220 yards. Now if B and C run 484 yards, who wins and by how much and: what is an Aryan? (No bad language please). -(Problem from A.G.T.,. Picton). In the Trenches Twenty-one men with 30 boys dig a trench 448 feet by seven feet and four feet in 15 days, while 45 men with 18 boys can do it in 30 days. What fraction of the work could be done in a day by a man and a boy? -(Problem from A.G.T., Picton).
