The rest of the farm was to be shared amongst his three children in the ratio 3 : 5 : 2. Given that the child who had the least share received 8 acres, calculate: (i) total acres the man left; (ii) number of acres the wife received. (b) The list price of a Television set is $1,600.00. It can be purchased by a deposit of $400.00 and the rest of the amount paid by 12 monthly instalments at 25% per annum simple interest.
