Given:
- Bought n items of product A at 1/5 rs each
- bought n items of product B at 1/4 rs each
He mixed the two items and sold each at 2/9 rs each.
He lost 3 rs in the above batch of articles.
Solution:
revenue = 2n* (2/9) rs = 4n/9 rs
cost = n/5+n/4 rs = n(1/5+1/4)
Profit = revenue-cost = 4n/9-n(1/5+1/4) = -3 rs
Solve for n
4n/9-n(1/5+1/4) = -3
factor out n
n(4/9-1/5-1/4)=-3
n(80-36-45)/180=-3
-n/180=-3
n=3*180=540
Total number of products bought
= n+n = 540+540 = 1080
5y + 4 = 6x-8 would be it
Answer:
float
Step-by-step explanation:
density = mass/voume
3g/6c.m. ^3
0.5g/c.m.^3 = 0.5g/mL^3
Since the density of water is about 1g/mL^3 and 0.5g/mL^3 is less than that, it will float
Answer:
8
Step-by-step explanation:
2(2)^2‒3(2*‒3)‒2(‒3)^2
2*4‒3(‒6)‒2(9)
8‒(‒18)‒18
8+18‒18
26‒18
8
i think it is easy to understand &i hope it will helps you
