Answer:
1)1 bottle =750 ml
46 bottles
= 750ml ×46
= 34,500 ml.
2) Cost of per metre tryoot cloth is rs 41.50
cost of 2.10 m cloth =₹41.50×2.10
=₹87.15
3)1kg =1ooog
Rate of 1kg of apple= Rs. 12.50
Rate of 2.2kg of apple= 12.50 multiplied by 2.2
= 275.00
So, the rate of 2kg 200g of apple=Rs. 275
4) mass=4.40kg
volume=5/1000=0.005
so we change it into all CGS system,
kg into gram
1kg=1000gm
or, 4.4kg=1000*4.4=4400gm
again,
m cube into cm cube
m cube=cm(100*100*100)=5000cm cube
now we now,
density=mass/volume=4400/5000=0.88gm/cm^3
5) cost of 3.2 kg ghee=448
cost of 1 kg ghee=3.2×448
= 1433.6
cost of 1 kg ghee=1433.6×1
=1433.6
Answer:
1. 750 × 46 = 34500 ml 2. 2.10 × 41.50 = 87.15
