<output>1/24 = around 0.041667</output>

<gadget id="calculator">2 * (1/24)</gadget>
<output>1/12 = around 0.083333</output>

<gadget id="calculator">(1/24) + (1/12)</gadget>
<output>1/8 = around 0.125</output>

inverse(add(inverse(24), multiply(const_2, inverse(24))))
"ratio of rates of working of a and b = 2 : 1 ratio of times taken = 1 : 2 a ' s 1 day work = 1 / 12 b ' s 1 day work = 1 / 24 a + b 1 day work = 1 / 12 + 1 / 24 = 3 / 24 = 1 / 8 a and b can finish the work in 8 days answer is c"
