Note 313 — Chapter VI
Reading edition
The formula for this computation is as follows:— If x pence = 1 rupee = 11·30016 grs. fine gold, 23·22 grs. fine gold = 1 dollar, D dollars = 1 pound sterling = 240 pence. Then x(11·30016 × 240)/(23·22 × D) = (11·680)/( D) pence. Cf. Rushforth, F. V., The Indian Exchange Problem, 1921, p. 9.
