Answer:

2. 4days = Rs800

1day = 800/4

= 200

11days = 200 *11

= Rs 2200

1. weight of 18 machines = 1260 kg

of 1 machine = 1260/18

= 70 kg

weight of 20 machines= 20*70

= 1400 Kg

4. cost of 12 (1 dozen) sharpners = Rs 48

cost of only 1 sharpner= 48/12

= Rs 4

cost of 36 sharpners= 36*4

= Rs144
