Logial Reasoning (CLAT) Arithmetical Reasoning

In a bag, there are some diamonds. In another bag, there are one fourth the number more than the number of diamonds in the first bag. If the difference in the number of diamonds in the first and second bag is 3, how many diamonds are there in the first bag?

Explanation:

Let diamond in Ist bag be x.
2nd bag = x * 1/4 + x
Diff. between no. of diamonds in both bags,
x - x/4 + x = 3
x - x + 4x/4 = 3
x - 5x/4 = 4
4x - 5x/4 = 3
-1/4x = 3
x = 12
Hence, option 3 is the correct answer.
