Goshia [24]

Answer:

let cp be x

mp= x+ (20% 0f x)= 1.2x

sp = mp -d%of mp= 1.2- 15% *1.2 =1.02x

profit = 40

sp-cp =40

1.02x-x=40

x=2000

cp =2000

mp= 1.2*2000=2400

Find the seventh term of the sequence 40, 0.4, 0.004, ....

natima [27]

Answer:

Answer: Option d. 4× $10^{-11}$

Step-by-step explanation:

In any sequence where ratio of the terms is given we always use the formula

A(n) = A(1) $r^{n-1}$

Here A(n) is the term n

A(1) is the first term

n= number of trms

and r = ration of the terms

Here the given sequence is 40,0.4,0.004........

So A(1) = 40

Ratio 'r' of second and first term is =0.4/40=1/100

We have to find 7th term so n=7

Now we put the values in the formula

A(7) = $40(1/100)^{7-1}$

= $40(1/100)^{6}$

= $40/100^{6} =40/10^{12}$

= 40× $10^{-12}$

= 4× $10^{-11}$
