p is able to do a piece of work in 10 days and q can do the same work in 12 days. if they can work together for 5 days, what is the fraction of work left? Choose the correct choice from the following:
A) 7 / 12  B) 5 / 12  C) 1 / 12  D) 3 / 12  E) 1 / 2
<gadget id="calculator">1 / 12</gadget>
<output>1/12 = around 0.083333</output>

<gadget id="calculator">1 / 10</gadget>
<output>1/10 = around 0.1</output>

<gadget id="calculator">(1/12) + (1/10)</gadget>
<output>11/60 = around 0.183333</output>

<gadget id="calculator">(11/60) * 5</gadget>
<output>11/12 = around 0.916667</output>

<gadget id="calculator">1 - (11/12)</gadget>
<output>1/12 = around 0.083333</output>

<result>C</result>
p is able to do a piece of work in 10 days and q can do the same work in 12 days. if they can work together for 5 days, what is the fraction of work left?
subtract(const_1, multiply(add(divide(const_1, 12), divide(const_1, 10)), 5))
"explanation : amount of work p can do in 1 day = 1 / 10 amount of work q can do in 1 day = 1 / 12 amount of work p and q can do in 1 day = 1 / 10 + 1 / 12 = 11 / 60 amount of work p and q can together do in 5 days = 5 × ( 11 / 60 ) = 11 / 12 fraction of work left = 1 – 11 / 12 = 1 / 12 answer : option c"
