Answer 1

Answer:

i) 35

ii) 12

iii) 70

iv) 2100

explanation -

i) the boatman said that he would carry the same kind of animals is every trip and  he would naturally like to take largest possible number each time .

so we can solve the first question by trail and error method which is trying out every option.

so we will see which is the largest no which divides 140,105 and 175 and we see that it is 35 hence the ans is 35

ii) we see that the boatman would take  largest possible number each time which is 3 so we would add 140,175 and 105 and divide it by 35 so the ans is 12

iii) so we just double the amount of each kind of animal which 210 goats , 280 donkeys , 350 cows , now from the given option choose the largest no that divides them all which is 70 , so the ans is 70

iv) u just have to find the lcm of 105,140,175
