If 7 ingots of iron weigh 112 tonnes, 4 ingots of cobalt weigh 104 tonnes and 3 ingots of aluminium weigh 105 tonnes, how heavy are 5 ingots of tin?
Answer65 tonnes; vowels are worth 3 and consonants are worth 5, added together and then multiplied by the number of ingots. Thus tin has 1 vowel (worth 3) and 2 consonants (worth 10). Added gives 13, then multiplied by 5 ingots = 65.
