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

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
