Question

dinesh and kabir have some coins. if dinesh gives kabir one coin they will both have the same of coins. if kabir gives dinesh one coin dinesh will have twice the number of coins that kabir has. how many coins does each boy have? ​

Answer 1

Let, dini have = x coins

kabir have = y coins

A/Q,

x-1 = y+1

x- y = 2 --------(1)

y-1=2(x+1)

y -1 = 2x +2

y-2x = 3 ----------(2)

(1) + (2)

-x = 5, x=-5

y = -7

Thus question is wrong as coins cant be negative
