800 cans of caviar

They say that teachers and textbook authors bully children. Well, I don’t know... My daughter and I are doing homework. Mathematics, 4th grade. And here is the problem we solve:

“Black caviar will be placed in 800 cans of 150 grams each. in each. How many jars will be needed for the same amount of red caviar if it is laid out in 200 grams? in each?

800 cans of black caviar?! 150 grams each?! And even 600 cans of red – and that’s exactly how many you’ll need! No, these authors are mocking adults after all! Thank you for not asking me to count 1,400 cans of caviar in rubles.
