Akhil and Sanjeev were given one basket of mangoes of equal number. Akhil added 2 mangoes to his basket while Sanjeev also added 2 mangoes to his basket. After some time their friend Sarath counted the number of mangoes in the two boxes and found equal number of mangoes in both. Did Sarath make any mistakes while counting?
There are 50 mangoes in a basket, 20 of which are unripe. Another basket contains 40 mangoes, with 15 unripe. If we take one mango from each basket, what is the probability of both being ripe?
