1)  

 Divide 480 in the ratio 4 : 6

4 parts Answer: 192

6 parts Answer: 288


SOLUTION 1 :

Given  :

 4 : 6 means the first quantity is 4 parts and the second parts quantity in 6 parts.

The total number of parts =  4+6

                                              =10

        10 parts =  480

         1 parts    =   48010

                         =48

4 parts    =  4 x 48

                      = 192

6 parts   =  6 x 48

                    =  288



2)  

 Divide 330 in the ratio 2 : 6

2 parts Answer: 83

6 parts Answer: 248


SOLUTION 1 :

Given  :

 2 : 6 means the first quantity is 2 parts and the second parts quantity in 6 parts.

The total number of parts =  2+6

                                              =8

        8 parts =  330

         1 parts    =   3308

                         =41.25

2 parts    =  2 x 41.25

                      = 83

6 parts   =  6 x 41.25

                    =  248



3)  

 Divide 340 in the ratio 3 : 6

3 parts Answer: 113

6 parts Answer: 227


SOLUTION 1 :

Given  :

 3 : 6 means the first quantity is 3 parts and the second parts quantity in 6 parts.

The total number of parts =  3+6

                                              =9

        9 parts =  340

         1 parts    =   3409

                         =37.7777777778

3 parts    =  3 x 37.7777777778

                      = 113

6 parts   =  6 x 37.7777777778

                    =  227
