4. A bag and a badminton racket costs 286. The bag costs 20 more than the badminton racket, how much is the cost of the badminton racket?

5. A table and two chairs cost 1,310. The table costs 470 more than the chair. Find the cost of the table and the chair.

6. Mr Chua bought a bed, a table, and a cabinet for 5320 athgether. The cabinet costs 140 more than the bed. The table cost 97 less than the bed. What was the cost of the cabinet?


Sagot :

4. 286 / 2 (Bag and Racket) = 143
    Racket + 20 = Bag
    20 / 2 = 10
    Bag = 143 + 10 = 153
    Racket = 143 - 10 = 133
    Total (Proof): 153 + 133 = 286
    Note: Formula only works when comparing 2 values.

5. Sorry. Does the table cost 470 more than one chair or both chairs?

6. Cabinet = Bed + 140
    Bed = Table + 97
    So Table < Bed < Cabinet.
    Table = 1662
    Bed = 1662 + 97 = 1759
    Cabinet = 1759 + 140 = 1899
    Total (Proof) = 1662 + 1759 + 1899 = 5320
