Which organisation publishes the Food Price Index (FFPI)?

A. UNICEF
B. FAO
C. IMF
D. World Bank

B. FAO (Food and Agriculture Organization)

The Food Price Index (FFPI) is a measure of the monthly change in international prices of a basket of food commodities. It is published by the Food and Agriculture Organization of the United Nations (FAO), which is a specialized agency of the United Nations that leads international efforts to defeat hunger and improve nutrition and food security. The FFPI is based on the average of five commodity group price indices, weighted with the average export shares of each of the groups for 2002-2004. The five commodity groups are cereals, vegetable oils, dairy, meat, and sugar. The FFPI is an important indicator of global food prices and is used by governments, researchers, and the private sector to monitor food price trends and assess the impact of food price changes on vulnerable populations.

Q: 8(a) CSS GSA 2023 Solved – Ali buys an oven for Rs.36800 and sells it at a gain of 8.5%. For how much does he sell it?

Formulas To be Used In Order To Solve This Problem

Gain % = (Gain X 100)/(C.P)

Gain = S.P – C.P

Given:

C.P = Rs. 36800

Gain% = 8.5%

To Find:

S.P = ?

Solution:

Gain % = (Gain X 100)/(C.P)

8.5 = (Gain X 100)/(36800 )

(8.5 X 36800)/100 = Gain

Gain = 3128

So,

 Gain=S.P-C.P

or

Gain + C.P = S.P

3128+36800= S.P

S.P = 39928

Ali Sold The Oven For Rs. 39928 at a gain of 8.5%.

Q:8(b) CSS GSA 2023 Solved – A card is drawn at random from a box containing 12 cards numbered 1,2,3,4,5,…,12. Find the probability of drawing.

(i) ‘8’

(ii) an even number

(iii) a perfect square

(iv) a negative number

(v) a number less than 13

Since, Sample Space or

S=1,2,3,4,5,6,7,8,9,10,11,12

Then,

(i) ‘8’

Solution:

S=1,2,3,4,5,6,7,8,9,10,11,12

Let A be the event selecting ‘8’, then n(A)=8

P(A)=(n(A))/(n(S))

P(A)=1/12 

As 8 numbered card is only one in the box, so the Probability of drawing a

card ‘8’ from box will be 1/12 

(ii) an even number

Solution:

S=1,2,3,4,5,6,7,8,9,10,11,12

Let A be the event selecting ‘even number’, then n(A)=2,4,6,8,10,12

P(A)=(n(A))/(n(S))

P(A)=6/12 

P(A)=1/2 

As Even number cards is six in the box, so the Probability of drawing a card an even number from box will be 1/2 

(iii) a perfect square

Solution:

S=1,2,3,4,5,6,7,8,9,10,11,12

Let A be the event selecting ‘a perfect square’, then n(A)=1, 4, 9

P(A)=(n(A))/(n(S))

P(A)=3/12 

P(A)=1/4  

As a perfect square number cards is 3 in the box, so the Probability of drawing a card a

perfect square from box will be 1/4  

(iv) a negative number

Solution:

S=1,2,3,4,5,6,7,8,9,10,11,12

Let A be the event selecting ‘a negative number’, then n(A)=0

P(A)=(n(A))/(n(S))

P(A)=0/12 

P(A)=0

As there is no any negative number card in the box, so the Probability of drawing a card a negative number from box will be 0

(v) a number less than 13

Solution:

S=1,2,3,4,5,6,7,8,9,10,11,12

Let A be the event selecting ‘a number less than 13’, then n(A)=1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12

P(A)=(n(A))/(n(S))

P(A)= 12/12 

P(A)= 1

As all numbers in the box are less than 13, so the Probability of drawing a card a

Number less than 13 from box will be 1.
