the tradesman marks his goods at such a price that he can deduct 4 % for cash and yet makes 20 % profit . what is the mp of an article which costs rs 1400

1750

Step-by-step explanation:

So it costs 1400 to make.  20% profit means he makes 1400*1.2 = 1680.

It also tells us he can deduct 4% of what it is actually marked to get to 1680.  So we want something that fits the equation x - x * .04 = 1680.  So let's solve for x.

x - .04x = 1680 Start by combining like terms

.96x = 1680 Then divide both sides by .96

x = 1750

Double check.  subtracting 4% from 1750 is 1750*.96 = 1680

Then we already showed that a 20% profit from 1400 is also 1680

i think it's b

step-by-step explanation:

because the graph is 2 above (0,0)

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
