Question

1 yard=91 cm and Rs.1 = 1.5 cent.The cost of 1 yard of rope is 1 cent,what is the cost of 1 m of rope ?

Answer 1

Cost of 1 yard= 1 cent
Cost of 91 cm =1 cent (because 1 yard=91 cm)
So,
Cost of 1 cm= 1/91 Cent
Cost of 100 cm (i.e 1 m)=100*1/91=100/91 Cent
So, cost of 1 m is 100/91 Cent=1.099 Cent
To change it in Rs.............1.5 Cent=Rs.1
So, 1 Cent=1/1.5
Cost of 1 m=0.67*1.099=Rs. 0.73
