Question

dinesh and kabir have some coins. if dinesh gives kabir one coin they will both have the same number 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

Lets say Dinesh has 'M' coins and Kabir has 'c' coins.

Now, when Dinesh gives one coin to Kabir, they have equal number of coins, so the equation becomes:

M - 1 = C + 1 , this means M = c + 2. (Equation a)

Also, if Kabir gives one coin to Dinesh, Dinesh will have twice the number of coins than Kabir:

M+ 1 = 2 C this means M = 2C - 1 (Equation b)

Comparing both equations (a and b); C+ 2 = 2C - 1. Hence C = 3.

So C = 3 and M = 5. Kabir has 3 coins and Dinesh has 5coins.
