One paper sheet can be used to create 8 paper boats or 6 paper planes. If total exact 80 paper toys are to be made, minimum how many sheets need to be used to make paper boats?	Choose the correct choice from the following answers.
A) 5  B) 4  C) 3  D) 2  E) 1
Let us say x sheets are used to create paper boats and y sheets are used to create paper planes. Since total 80 paper toys are to be created, 8x + 6y = 80.   =&gt; 8x = 80 - 6y   =&gt; x = 10 - (6/8)y   =&gt; x = 10 - (3/4)y   To minimize x, we need to maximize y. And y needs to be multiple of 4.   y = 4, x = 10 - (3/4)4 = 7   y = 8, x = 10 - (3/4)8 = 4   y = 12, x = 10 - (3/4)12 = 1   Beyond this, x will become negative for greater values of y. So, minimum 1 sheet is required to be used for creating paper boats.   Answer: 1
