Can I know how u work it out? Need to explain to my child. Thanks.

We have 11.1kg÷300g=37, and 48.1-11.1=37. Since there is an even number of packets , we can set as 37×2=74 packets. 37kg÷74=0.5kg. Hence the mass of each tin=0.5kg + 300g=0.8 kg, option 3

Sorry if it's a bit long

Probably need to explain how I get the boxes. 80 percent more. Assume base is 5 box. This means apple has 9 boxes and orange has 5 boxes. Once you can appreciate this, you will be able to understand.

First u need to know set which fruits u want it to be 100%. In this case, we let oranges be 100% so number of apples will be 80%. After selling 60% of oranges, 40% of oranges was left. 80% - 40 % as there are 42 more apples than oranges. Therefore 40% = 42 . Total apples = 84 and total oranges = 105

Thanks but don't understand the method.

Can explain in percentage.? Please

Ok thank you very much..
