a. notional price = number of cntract * price
= 4* 1200
= 4800
b. initial margin = price * initial margin percentage
= 1200* 0.10
= 120 per contract
ie, for 4 contracts = 120*4
= 480
c. Marginal call price =( (1+initial margin)/(1+ maintanance margin ) ) * price
= ( (1 +0.10) /(1+0.80) ) * 1200
= 733.33 per contract
ie, for 4 contracts, = 733.33* 4
= 2933.32
