Price Elasticity of Demand is Infinity ( ed = Infinity )


Price Elasticity of Demand is Infinity ( ed = Infinity )

Change in Quantity Demanded will not change the price.

This is also called as Perfectly Elastic Demand Curve

Example:- Seasonal Goods

Price Elasticity of Demand is Zero ( ed = 0 )


Price Elasticity of Demand is Zero ( ed = 0 )

Any Change in Price will not lead to any change in Quantity.

It is also called as Perfectly Inelastic Demand Curve.

Examples:- Medicines, Salt, etc.

Elasticity of Demand Equal to 1 ( ed=1 )

When the ratio of Change in Price is equal to the ratio of change in Demand, then ed=1

It is also called as Unitary elastic/unit elastic.

Question of the day 29-7-2014


Question of the day:
Which of the following is a prime number
A. 9
B. 3
C. 4
D. 8

View Answer

Answer: B. A prime number is a natural number greater than 1 which has no positive divisors other than 1 or itself.
So from above options 3 is that number

Price Elasticity of Demand Less Than 1 (ed<1)


Elasticity of Demand Less than 1 ( ed<1 )

A big change in Price, leads to small change in Demand. It is also called as Less Elastic Demand Curve.

Examples: All Necessity Goods.

Elasticity Of Demand Greater Than 1 (ed>1)
This occurs when a small Change in price leads to big change in Demand.
This is also called as Highly Elastic Demand Curve.
Example:- Luxury Goods.

Question of the day 28-7-2014


Question of the day:
A passenger train running at the speed of 80km/hr leaves the railway station 6 hours after a goods train leaves and overtakes it in 4 hours. The speed of the goods train is:
(A) 32 km/hr
(B) 40 km/hr
(C) 50 km/hr
(D) 60 km/hr

View Answer

Answer: (A) Let the speed of goods train = x km/hr
Distance travelled at the speed of 80 km/hr in 4 hours.
= 4 × 80 = 320 km
Therefore, x= 320/10 = 32 km/hr

Question of the day 27-7-2014


Question of the day:
1200 amounts to 1632 in 4 years at a certain rate of simple interest. If the rate of interest is increased by 1%, it would amount to how much?
(A) 1635
(B) 1644
(C) 1670
(D) 1680

View Answer

Answer: (D) Extra interest received in 4 years if the rate of interest is increased by 1%
= (4×1)% of 1200
= 4% of 1200
= Rs. 48
Total amount received in 4 years if the rate of interest is increased by 1%
= 1632 + 48
= Rs. 1680

(A) 100
(B) 92
(C) 91
(D) 50

View Answer

Answer: (C) No. of digits required
= [{(9–1)+1}×1 + {(50–10)+1}×2] = 9 × 1 + 41× 2 = 9+82 = 91

Question of the day 24-7-2014


Question of the day:
If there is a reduction in the number of workers in a factory in the ratio 15 : 11 and an increment in their wages in the ratio 22 : 25, then the ratio by which the total wages of the workers should be decreased is
(A) 6 : 5
(B) 5 : 6
(C) 3 : 7
(D) 3 : 5

View Answer

Answer: (A) Required ratio = (15 × 22) : (11 × 25)
= 330 : 275
= 6 : 5

Question of the day 23-7-2014


Question of the day:
A reduction of 10% in the price of wheat enables a man to buy 50 gram of wheat more for a rupee. How much wheat could originally be had for a rupee ?
(A) 400 grams
(B) 500 grams
(C) 450 grams
(D) 350 grams

View Answer

Answer: (C) 10% reduction in price
=> 11.11% increase in quantity
(when expenditure is constant)
A.T.Q,
11.11% of original amount of wheat = 50 gm
=> Original amount (ie.100%) of wheat
= (50 × 9) gm
= 450 gm
