Why my recieved dividend is low?

Today i received 1120.55 Rs dividend which is from OGDC as my brother told me, since he also bought shares of OGDC and 24 March was the date I checked.. He received total amount of the dividend while i received about 87.76 Rs less than expected.. My total shares of OGDC are 351, and dividend was about 4.05rs per share... I did the mathx total amount is 1421 and after total tax deduction it should be about 1208 Rs... And I received 1120.55.... 1208-1120 = 88 Rs.. Where did the 88 Rs went away??
