Question

plz answer 'A' and 'B' tankers contain 840 litres and 420 litres of oil, respectively. What is the maximum capacity of a container which can measure the oil of both the tankers an exact number of times?
(a) 840 litres (b) 20 litres (c) 40 litres (d) 420 litres

Answer 1

Answer:

d) 420 litres

Step-by-step explanation:

If you add 840 and 420 you will get 1 260 which is a multiple of 420 given that 840=2x420 and 420=1x420 which means that this is the highest possible value that wouldn't leave a surplus
