there is a loss of 20% by selling a photocopy machine for rs 60000 at what price will the machine be sold to gain 12% find it

notsponge [240]

Answer:

Step-by-step explanation:

Loss is 20%

S.P=Rs60000

C.P=S.P*100/100-loss%

=60000*100/80=Rs75000

So he brought is at Rs75000

Now he wants 12% profit

S.P=(100+profit%)/100*C.P

=100+12/100*75000

=112/100*75000=Rs 84000

He will have to sell Rs14000 more to gain profit of 12%

The time (in minutes) required to learn the procedure for performing a certain task is uniformly distributed on the interval fro

PtichkaEL [24]

Answer:

$P( X > 46) = 0.7 \ minute$

$\mu = 42 \ minute$

Step-by-step explanation:

From the question we are told that

The procedure for performing a certain task is uniformly distributed on the interval from( a = 32 )minutes to (b= 52) minutes

Generally the cumulative distribution function for continuous uniform distribution is

$F(x) = \left \{ {{0 \ \ \ \ \ for \ x \ x < a} \atop {\frac{x-a}{b-a} } \ \ for \ a \le x \ge b} \atop {1 \ \ \ \ \ \ \ for \ x > b }\right.$

Generally the probability that it takes more than 46 minutes to learn the procedure is mathematically represented as

$P( X > 46) = F(46) = \frac{46 - 32}{52-32}$

=> $P( X > 46) = 0.7 \ minute$

Generally the average time required to learn the procedure is mathematically represented as

$\mu = \frac{a + b}{2}$

=> $\mu = \frac{32 + 52}{2}$

=> $\mu = 42 \ minute$
