Question

A and B each have a certain number of mangoes. A says to B, "if you give 30 of your mangoes, I will have twice as many as left with you." B replies "if you give me 10, I will have thrice as many as left with you." How many mangoes does each have?​ Solve it​

Answer 1

Answer:

Step-by-step explanation:

let A and B have x and y mangoes respectively.

if A gets 30 mangoes A will have x + 30 mangoes and B will have y - 30  

according, to the problem, x + 30 = 2(y - 30)

                                     or, x + 30 = 2y - 60

                                     or, x - 2y = -90 .(i)

Also,                                  3(x - 10) = y + 10

                                     or,3x - 30 = y + 10

                                     or, 3x - y = 40 .(ii)

Solving eqn(i) and eqn(ii) we get x = 34 and y = 62

So A and B has 34 and 62 mangoes initially.
