Answer
Answer (as printed):
Explanation
Let the number of one-rupee, 50-paise and 25-paise coins be $5x, 6x$ and $8x$ respectively. Then, sum of their values $=₹\left(5x+\frac{50\times 6x}{100}+\frac{25\times 8x}{100}\right)=₹(5x+3x+2x)=₹10x$. $$\therefore \quad 10x=210 \Rightarrow x=21.$$ So, number of one-rupee coins $=5\times 21=105$; number of 50-paise coins $=6\times 21=126$; number of 25-paise coins $=8\times 21=168$.
