Assume the number of kgs of minced chicken bought = u

If you divide u kgs of chicken into 1/5kg packets, the number of packets = 5u
If you divide u kgs of chicken into 1/7kg packets, the number of packets = 7u

Then 7u = 5u +10 ----> 2u = 10 --> u =5

So the number of kgs of minced chicken bought = 5kg

Hi

Diff between the two pkts --> 1/5 - 1/7 = 2/35
weight of extra 10 pkts --> 1/7 * 10 = 10/7
No. of 1/5 kg bags --> 10/7 / 2/35 = 25
Total weight --> 25 * 1/5kg = 5kg

Hi,


Pls assist below question. The answer given in the answer sheet is 16r but I feel a bit not right (hope I am wrong).

"Leroy had only $9 and he needed to buy 85 magnets. His father gave him another $r. The magnets were sold in pack of 5 for $r. How much more money did he need to pay for all the 85 magnets ?"

I need to explain to my son but I wonder what happen to the $9 if the answer is 16r.

Thnks

Hi

Jose --> 1 unit + 54
Nari --> 1 unit
Andy --> (5 x 2units) + (54 x 5) = 10 units + 270

Diff between Andy & Mari --> 9 units + 270
9 units + 270 --> 630
9 units --> 360
1 unit --> 360 / 9 = 40

Jose --> 40 + 54 = 94
