Answers (1)

amount of rice purchased by Ravi = 5 kg 400 g.

amount of sugar purchased by Ravi = 2 kg 20 g.

amount of flour purchased by Ravi = 10 kg 850 g.

As we know.

For adding two numbers their unit must be the same.

So,

5\:kg+400g=5kg+\frac{400}{1000}kg

                           =5kg+0.4kg

                           =5.4kg

Also,

2\:kg+20g=2kg+\frac{20}{1000}kg

                           =2kg+0.02kg

                           =2.002kg

And,

10\:kg+850g=10kg+\frac{850}{1000}kg

                           =10kg+0.85kg

                           =10.85kg

So,

The total weight of the grain Ravi purchased = 5.4 kg + 2.002 kg + 10.85 kg

                                                                        = 18.270 kg

 

Hence Ravi purchased total grain having the weight of 18.270 kg.
