In which of the market form, supplier chooses to sell at market determined prices
Monopoly
Monopolistic competition
Perfect competition
Oligopoly
In a oligopoly market, there exists few sellers. This is because
low profit margins
there are entry barriers
demand for their products is limited
none of above
Price elasticity is perfect competition is
greater than one
less than one
zero
infinite
There is only one Electronic showroom in a village, as it is their monopoly, they decided to change price of an electronic item from Rs.10,000 to Rs.13,500. This will
affect their demand as some consumers may chose to buy from other shops in that village
affect their demand as some consumers may chose not to buy that particular product
will not affect their demand and all their consumers will continue to buy that product
none of above

a monopoly firm faces demand curve where price elasticity is
zero
one
infinite

Downward sloping demand curve is faced by a firm in _______ market form
Monopolistic competition and monopoly

In both monopoly market form and monopolistic competition demand curve is downward sloping but in case of monopolistic competition it will _______ as compared to monopoly
flatter (relatively more elastic)
steeper (relatively less elastic)
a monopolist can fix price of his product but if keep too high price he may not be able to sell much quantity and if he has to sell higher quantity he will have to keep prices reasonable. Therefore we can say a monopolist has _______ control over its price

entry barriers
product differentiation
absence of competition

few sellers sell differentiated product
large number of sellers sell differentiated product
perfect competition is when

If a firm is making losses in the short run and it decides to shut down, then it will incur
zero loss
loss equal to total costs
loss equal to variable costs
loss equal to fixed costs
a firm incurring loss in the short run will shut down if it is not able to recover even
variable costs
fixed costs
total costs
none
M/s XYZ limited has total variable cost of Rs.50,000 and Its total fixed costs is Rs.20,000. Should the firm shut down if its total revenue is Rs.65,500.
yes, as it is incurring net loss of Rs.4,500
no, as it is able to recover total costs
no, as it is able to recover variable costs fully and some part of fixed costs as well
none of above
If a firm decided to exit the market, it is possible in the
short run
long run
either short run or long run
can't exit
a firm cannot exit the market in the short run because
fixed factors cannot be changed in the short run
exiting in the short run will have huge costs
exiting in the short run is not allowed under the law
none
a firm may exit the market in the long run and in that case it will be able to avoid
variable costs
fixed costs
all costs
none
There are 100 firms in an industry which operates in monopolistic competition, all of which are making huge profits, what is most likely to happen
new firms will enter the market and thereby keep earning similar profits
new firms will enter the market and thereby profits of existing firms as well as new firms will not as much as it used to earlier
new firms will enter the market and thereby profits of all the firms would increase further
some of the existing firms will leave the market and thereby profits of remaining firms would fall down
In an industry where there is super normal profit, there new firms will continue to enter as long as
all the firms does not start making losses
all the firms does not start earning normal profits only
some of the existing firms does not exit the market
none of above
In _______ market form, if existing firms are earning super normal profits, then this will not last in the long run due to entry of new firms

entry of new firms ; exit the market ; normal profits
exit the market ; entry of new firms ; normal profits

Equilibrium price and quantity demanded is
₹ 40 ; 520 units

In this graph the area darkened in green is showing
