before:E&M=1u

After:E*3=6u,M=1u

6/3=2(due to internal transfer) 9=2u-1u=1u

6/3=2(1u during internal transfer)

at first total units:2(each)

total :2*9=18(each)

Length of bigger square is 10cm Length of smaller square is 3 cm Area of bigger square is 100cm sqm Area of smaller square is 9sqm Shaded area will be 91 sqm.

Length can't be 10cm cos qn states that the length is 1 digit number.

I see. Thanks Yueh Mei.

28+24=52 as well. 49-36=13cm2.Can there be more than one ans?

Yes. More than one answer is possible.

Hi, MeiYee Leong. Here are two hints to solve this problem. Hint 1: compare the mass of the apple and banana, and the carrot and banana. How much heavier is the carrot than the apple? Hint 2: draw the model of the carrot and apple. You know how heavier the carrot is than the apple AND you have their total mass. So, once you solved hint 1 and hint 2, you will get the mass of the carrot. :)

Hi Shaoyang Brandon, the apple is 190g.Thanks.

Yup, you got the mass of the apple! (Y) Don't forget about the mass of the carrot. :) If you are feeling ambitious, you can find out how heavy the banana is. :)

Yup..got it for all

Answer is 42kg

18kg is for 3 days. So should be 18/3 = 6kg. Then 7 x 6kg = 42kg

Ya ... ans is 42 kg

How to get 18kg?

Thank you Izam Marwasi

Thank you Bee Yen.

after CA=3u CB=1u 50.36/4=12.59 12.59x3=37.77 37.77+9.05=46.82=46.8

Thank you.
