Thank you
The question asked for cross elasticity of good Y against PRICE of good X. The key word is we are looking at the QUANTITY of Y and the PRICE of X.

Old Qy is 20 and new Qy is 30

Old Px is 8 and new Px is 10.

My way of calculating is (Qnew - Qold/ Qold) / (Pnew-Pold/Pold)

Once you solve that, you get an answer of 2. The equations in the options all have 2 in their range except for A so you eliminate A.

C is the most suitable answer because it has the number 2 in it.

Hope I helped :)

Thank you very much! :)

Q17. Answer is B but im getting A :/
According to Marshall Lerner condition when PED of exports plus PED of imports is less than 1 , then a fall in value of currency (depreciation) will further deteriorate or worsen the trade. It is in option A where 0.5 + 0.25 = 0.75 which is less than 1. In all other options it is 1 or greater than 1.
Hope u got it.

PED is always negative but we need not to put negative sign as it is understood.XED for substitutes is positive and for complements it is negativeYED for normal and luxurious goods is positive and for inferior and giffen goods it is negative
