@Sajjad1994,as and when possible could you share the working of how the values of f-16 and eurofighter was derived?
Thanks.
Read the statements carefully, break them into parts and write down the information.
Cost of one F-16 = 20,000 $
Cost of one Sukhoi = 8,000 $
Cost of one Eurofighter = 5,000 $
Calculate F-16 only- USA got one third of F-16
- The number Of F-16 that USA & Russia got together was 50% more than that of France and England together had.
It means 60% of F-16 are taken by both USA and Russia and 40% are taken by both France and England. If one third (33%) F-16 taken by USA then Russia will take 27% of F-16.
- Russia got 8 F-16
It means 8 F-16 are 27% of the total F-16 and total number of F-16 is 30. 1/3 are taken by USA which is 10.
- USA got 10 F-16.
- England got 7 F-16
as total F16 are 30 the remaining will go to France.
- France got 5 F-16
Now calculate Sukhoi only
- France received 50% Sukhois as the 50% of his total planes.
- USA and Russia got equal number of Sukhois
- England got 20 Sukhois less than that of France.
What we can infer from the above statements is that 50% Sukhoi goes to France, 20% to USA, 20% to Russia and 10% to England.
- England got 20 Sukhois less than that of France.
We can infer from above statement that 20 Sukhois consists of 40% of total Sukhois as France has 50% Sukhoi and England has 10%.
- Total number of Sukhoi is 50
- France has 25 Sukhoi (50%) It also means total number of jets of France is 50
- England has 5 Sukhoi
- USA and Russia each have 10 Sukhoi
Now calculate Eurofighters only
- Half of USA jets are Eurofighters
USA has 10 F-16 and 10 Sukhio then it has 20 Eurofighters.
- USA has 20 Eurofighters
- England got twice the Eurofighter than that of Russia but 20% less than that of France.
If total number of jets of France is 50 and it has 25 Sukhoi and 5 F-16 then France has 20 Eurofighters.
- France has 20 Eurofighters
England got 20% less Eurofighters than France we can infer that:
- England has 16 Eurofighters
England got twice the Eurofighter than that of Russia, it means Russia has 8 Eurofighters.
- Russia has 8 Eurofighters.
All of the jets are now allocated to all four countries and below is the summary.

Now solve the questionsQ-1. Difference between values of USA's planes & values of England's plane in $380,000 - 260,000 = 120,000 = 0.12 Millions = A
Q-2 if France wants to exchange all his Sukhois with the f-16 then who can exchange with her f-16 in term of monetary value:The price of 25 Sukhoi = 25*8,000 = 200,000 = The price of 10 F-16 = 10*20,000 = 200,000 = USA = A
Q-3 the value of planes of England is how many % less than that of France:Value of jets of England = 260,000
Value of jets of France = 400,000
Difference = 400,000 - 260,000 = 140,000
\(\frac{140,000}{400,000}*100 = 35% = A\)
Q-4 the value of Eurofighter and Sukhois together isValue of Eurofighters = 320,000
Value of Sukhoi = 400,000
Total = 320,000 + 400,000 = 720,000
Value of F-16 = 600,000
Difference = 720,000 - 600,000 = 120,000
\(\frac{120,000}{600,000}*100 = 20%\) = A
PS: there was a little typo in the question which I have edited.
