Hi all,


Appreciate anyone free to solve a maths problem as follow:-

Some apples and oranges were packed into blue and red boxes. There were 12 more blue boxes than red boxes. Each blue box contained 120 apples and each red box contained 150 oranges. Given that there were 120 fewer apples than oranges in total, how many apples were there?

Many thanks,
Stary :?

Need help on this question. Please explain to me :? Thanks


Mr Lim packed 387 apples. Each apple had a mass of about 24g. He put them into three different baskets. The mass of apples in the Basket A was 3 times that of the apples in C. The mass of apples in Basket B was twice that of the apples in Basket C. The mass of the empty Basket C was 140g. What was the total mass of Basket C and the apples in it?

The mass of apples in Basket B was twice that of the apples in Basket C. The mass of the empty Basket C was 140g. What was the total mass of Basket C and the apples in it?

Let me try :
Basket A ~ 3 units
Basket C ~ 1 unit
Basket B ~ 2 units

Total Units = 6
Total mass of apples = 387 * 24 = 9288g
I unit = 9288/6 = 1548
Hence TOtal mass in Basket C is 1548 + 140 = 1688g. Appples alone is 1548g.
