Question

Sam packed 42 kg of rice into one big bag and six small ones which were of the same size the small bags .each contain 1/10 of the rice .how many kilograms of rice did the big bag contain?

Answer 1

we are given

Sam packed 42 kg of rice

So, total amount of rice =42kg

And there are six small bags

each contains 1/10 of the rice

So, rice on each bags is

$=\frac{1}{10}\times 42$

$=4.2$kg

so, total rice in 6 bags is

$=6\times 4.2$kg

$=25.2$kg

so, the rice in big bag = ( total amount of rice )-( total rice in six small bags)

we can plug values

and we get

so, the rice in big bag is

$=42-25.2$

$=16.8$kg..............Answer
