1. Answer:

   Time taken by one boy to complete the work=16days

   Time taken by one girl to complete the work=48days

   Step-by-step explanation:

   2+6=1

   x y 4

   2u+6v=1/4 (i)

   1+5=1

   x y 6

   2+10=1

   x y 3

   2u+10v=1/3 (ii)

   on subtracting (i) from (ii), we get:

   4v=1/12

   v=1/48

   or y=48

   Putting the value of y in (i), we get:

   x=16
