u borrow rm50 frm fren A, rm50 from frenB..then u bought a pair of shoes costs rm97...
the balance is rm3, then u pay fren A & B rm1 each...then u keep the left over rm1....
so u still owe them rm49 each right...
49+49=98
then u add the rm1 that u kept..rm98+rm1=99...but y the ans is not rm100??
same condition but this time the item that u bought is rm95...the balance will be rm5...den u wil pay ur frens rm1 each....den u will keep the rm3....

U borrow RM50 from 2 frens, then u return RM1 to them. So now u owe Rm49 from each person and u r holding RM1. But u still have to return RM49 to them.
Now if u directly borrow 97 from 2 frens. Then each of them u borrow 97/2 = 48.5. So u have to return them RM48.5. Compare to the case u borrow RM49. Although u get back 1 buck. But u pay RM0.5 more to each ppl. RM0.5 X 2 =1.
2nd question also the same theory.
