Question 126
P and Q have a certain number of Mangos. P says to Q: “If you give me 30 of your mangoes. I will have twice as many as left with you”. Then Q replies as “If you give me 10 mangoes, I will have thrice as many as left with you”. Then how many mangoes P had at the beginning?
Solution
Let P have p mangos and Q have q mangoes
Condition 1: p+30 = 2(q-30)
Condition 2: q+10 = 3(p-10)
Solving both these equations we get p=34 and q=62
