Correct option is (C) m : n Sum of m arithmatic means between a and b \(=(a+d)+(a+2d)+.......+(a+md)\) \(=ma+d\,(1+2+.....+m)\) \(=ma+d\,\frac{m(m+1)}2\) \(=ma+\frac{m(m+1)}2\times\frac{b-a}{m+1}\)     \((\because d=\frac{b-a}{m+1})\) \(=ma+\frac{m}2\,(b-a)\) \(=\frac{2am+mb-ma}2\) \(=\frac{m(a+b)}2\) \(\therefore\) Sum of n arithmatic means between a and b \(=\frac{n(a+b)}2\) \(\therefore\) Required ratio \(=\cfrac{\frac{m(a+b)}2}{\frac{n(a+b)}2}\) \(=\frac ma=m:n\)
