Answer 1

metres of cloth                  cost  
       52/7                              281/3
         1                                    ? (x)
this is direct proportionality. there fore, by cross multiplying,
52/7 (x) = 281/3 (1)
⇒ x = 281/3× (52/7)
⇒x = 12.60
therefore cost of 1m cloth = 12.60 rupees
