The sum of the series $5.05 + 1.212 + 0.29088 + ...\,\infty $ is
The sum of the series $5.05 + 1.212 + 0.29088 + ...\,\infty $ is
(d) Clearly it is a infinite $G.P.$ whose common ratio is $0.24.$
$\therefore {S_\infty } = \frac{a}{{1 - r}} $
$= \frac{{5.05}}{{1 - 0.24}} = 6.64474$.

A person writes a letter to four of his friends. He asks each one of them to copy the letter and mail to four different persons with instruction that they move the chain similarly. Assuming that the chain is not broken and that it costs $50$ paise to mail one letter. Find the amount spent on the postage when $8^{\text {th }}$ set of letter is mailed.
