Raman has 2 urns. Both these urns have some pebbles. If 20 pebbles from urn B are shifted to urn A then, the number of pebbles in each urn become interchanged. But if 10 pebbles from urn A are put into urn B, then number of pebbles in B are twice the number in A. How many pebbles do A and B have respectively?
Answer & explanation
Correct answer: option 3
These types of questions are answered with the help of options:
Option1: A = 60 and B = 40 In this case condition 1 and 2 are not being fullfilled
Option2: A = 80 and B = 100 In this case condition 1 and 2 are not being fullfilled
Option3: A = 50 and B = 70 In this case condition 1 and 2 both are being fullfilled. Thus, we need not check any other option and mark this as the final answer.
