Hi..
the equation we get is \(L=\frac{E}{2}+10\)

lets see the statements..
Statement 1: The difference between the number of chocolates than Lampard and Essien had was less than 30.
EITHER \(L-E<30.....\frac{E}{2}+10-E<30.....\frac{E}{2}>-20....E>-40...\) basically means E>0 or E=0... so E could have any number..
OR \(E-L<30.....E-\frac{E}{2}-10<30.....\frac{E}{2}<40...E<80...\) again E could be LESS than 20 or EQUAL or MORE than 20
Insuff..

Statement 2: The total number of chocolates than Lampard and Essien had was greater than 5/2 of the number of the chocolates with Essien
this is second equation ..
we have TWO variables and TWO different equations, here we can find the answer inspite of an inequality as we are not looking for exact value
ans can be found..
sufficient..

but lets find value..
\(L+E>\frac{5E}{2}.....L>\frac{3E}{2}\)

substitute in main equation..
\((>\frac{3E}{2})=\frac{E}{2}+10....\frac{3E}{2}<\frac{E}{2}+10......E<10\)

Hi chetan2u
i have a doubt in St:2 analysis
it is mentioned that The total number of chocolates than Lampard and Essien had was greater than 5/2 of the number of the chocolates with Essien
i thought the equation would be as L + E >5E/2 because it is mentioned " Greater than"
where as you have mentioned L+ E = 5E/2.

Kindly let meknow the flaw in my understanding.

hi..
raju you are absolutely correct about GREATER THAN..
its only if I took equal to I would get MAX value of E and the actual value will be less than 10.
however I have made answer more clear now
