These problems are different.
They use the same math you already know — but wrapped in ways you haven't seen before. There's no rush. Think slowly. Write your reasoning. The answer matters less than HOW you got there.
🎨 Unfamiliar Territory
A baker is making 100 laddoos for a party. He wants to pack them into bags so each bag has roughly the same number of laddoos. He knows each laddoo weighs about 20 grams. Suggest a weight range for each bag, so they're easy to carry but still have plenty of laddoos!

A basket of mangoes weighs 3 kg. You eat 2 mangoes. Each mango weighs 150 grams. First, calculate the total weight of the 2 mangoes you ate in grams. Next, convert the basket's initial weight into grams. Then, subtract the weight of the mangoes you ate from the basket's original weight. Finally, what is the new weight of the basket in kg?

Three friends, Ali, Ben, and Cathy, each have a different toy car. Ali's car and Ben's car together weigh 350 grams. Ben's car and Cathy's car together weigh 400 grams. Ali's car and Cathy's car together weigh 450 grams. What is the weight of Ben's car?
Think about what constraints the problem gives you. Write down what you KNOW for sure, then work from there. Often, trying small numbers first reveals a pattern.
