Solution:
Twice of Ramesh's sweets is 8+12 = 20 sweets. Each of them had 20/2 +12 = 22 sweets at first.

Thanks for the reply but why 8+12?

The answer sheet says 22 sweets for each child.


Do we always presume that 12+8 belongs to the 2 units? if this is so then 1 unit is 10 sweets, so both should have 10 sweets each at first. Why 22 sweets? Sorry I m slow in maths.

Hi Peapot,

Maybe you are shy in contacting me... keke

Since you know that 1 unit is 10 sweets now, but the question ask how many sweets do they each have at first..
Ramesh lost 12 sweets, and she had 10 sweets left now..
Therefore, 12 + 10 = 22.
Ramesh had 22 sweets at first.

Hi,


I got a question to ask:

I always thought that when you see the word 'place' ie. The digit 8 is in the _________ place, it means answers like 'thousands', 'hundreds' etc are required; and when they ask for 'value' ie. What is the value of '8', it means it wants answers like '8000'.

How about 'place value'? 'Thousands' or '8000'?

You thought right in the first place. Pardon the pun. Take for example a given set of numbers - 18452. For place value, it means how much the digit 8 represents which in this case 8000 or 8 thousands. Another way this question is asked is \"What does the digit '8' stands for?\"

But several assessment books state the place value is just thousands in this case. Which one is correct? Thousands or 8000? Very confusing.

Thank you in advance

I was going thro a question in an assessment book and the answer given was just 'thousands', which meant it wanted the 'place', essentially different from '8000' or '8 thousands' which is the 'value'.

It also means that the question 'What does the digit '8' stand for?' is different from 'What is the place value of the digit '8'?'.

Ya, I have seen thousands in most of the assessment book. ????
