10 hens are purchased for _67.92_
let the missing digits be = a and b respectively.
total cost of 10 hens = C = 100 * a + 67.92 + b/1000
cost of one hen = C/10 = 10 a +6.792 + b/10,000
= a6.792b
or a6.79 rounded up to 2nd decimal place.
a is 1 or 2 or 3 ....9..
the cost of a hen is 6.79 or 16.79 or 26.79 or ..... 96.79
