Answer:

33) 20(2/3)%

34) 13%

Step-by-step explanation:

Cost of land = 480000

Sold 2/5 land and the amount he got = 480000 * 2/5

                                                             = 192000


Loss of 6% percent =  192000(1-6/100)

                                = 192000(94/100)

                                = 1920 * 94

                                = 180480


To gain 10% profit  = 480000 * 1.1

                              = 528000


Selling 3/5 of land = 528000 - 180480

                              = 347520


Cost of remaining 3/5 land = 480000 * 3/5

                                            = 288000.


Here, Selling price > Cost price. So, gain has occurred.

We know that Gain = Selling price - Cost price

                                = 347520 - 288000

                                = 59520.


We know that Gain% = (Gain/CP) * 100

                                  = (59520/288000) * 100

                                  = 20.6667

                                  = 20 (2/3)%.


Therefore, Gain = 20 (2/3)%.

Given, Cost price of sugar = 4500.

Cost price of (1/3) of sugar = (1/3) * 4500

                                              = 1500


Gain = 10%.

We know that SP = [(100 + Gain)/100) * CP

                              = [110/100] * 1500

                              = 1650


Given, total Gain = 12%.

We know that SP = [(100 + Gain%]/100] * 4500

                             = [112/100] * 1500

                             = 5040.


Remaining Cost price = 4500 - 1500

                                    = 3000


Remaining Selling price = 5040 - 1650

                                        = 3390.


Here, Selling price > Cost price.So, Gain has occurred.

Gain = S.P - C.P

        = 3390 - 3000

        = 390.


Gain% = (Gain/CP) * 100

           = (390/3000) * 100

           = 13%.


Therefore, Gain = 13%.

Step-by-step explanation:

Cost of land = 480000

Sold 2/5 land and the amount he got = 480000 * 2/5

= 192000

Loss of 6% percent =  192000(1-6/100)

= 192000(94/100)

= 1920 * 94

= 180480

To gain 10% profit  = 480000 * 1.1

= 528000

Selling 3/5 of land = 528000 - 180480

= 347520

Cost of remaining 3/5 land = 480000 * 3/5

= 288000.

Gain = Selling price - Cost price

= 347520 - 288000

= 59520.

Gain% = (Gain/CP) * 100

= (59520/288000) * 100

= 20.6667

= 20 (2/3)%.
