A) 5 hours  B) 3 hours  C) 6 hours  D) 12 hours  E) 15 hours
<gadget id="calculator">3 / 4</gadget>
<output>3/4 = around 0.75</output>

<gadget id="calculator">(3/4) * 2</gadget>
<output>3/2 = around 1.5</output>

<gadget id="calculator">(3/2) * (3/4)</gadget>
<output>9/8 = around 1.125</output>

<gadget id="calculator">(9/8) * 2</gadget>
<output>9/4 = around 2.25</output>

<gadget id="calculator">(3/2) - (9/8)</gadget>
<output>3/8 = around 0.375</output>

<gadget id="calculator">(9/4) / (3/8)</gadget>
<output>6</output>

a man walking at 3 / 4 th of the speed, reaches his office late by 2 hours. what is the usual time?
divide(multiply(multiply(multiply(divide(3, 4), 2), divide(3, 4)), 2), subtract(multiply(divide(3, 4), 2), multiply(multiply(divide(3, 4), 2), divide(3, 4))))
at 3 / 4 th of speed he is late by ' 2 hrs ' x - 3 / 4 ( x ) = 2 x = 8 so 8 - 2 = 6 hrs ( since 2 hrs late ) answer : c
