You can put this solution on YOUR website! The naira (sign: ₦; code: NGN) is the currency of Nigeria. It is subdivided into 100 kobo.

It must be 2 more than the least common multiple of 9, 10, and 15
9 = 3×3
10 = 2×5
15 = 3×5
LCM(9,10,15) = 2×3×3×5 = 90
Therefore 90+2 or 92 kobo is the least sum of money.
