                  Shella has taken a bank loan to initiate floriculture on 100 m  of vacant land.
                  She wants to plant roses in one-half of the area. The remaining field, she wants
                  to use for marigold and sunflower cultivation, exactly in halves.
                  Based on the above information, answer the following questions by choosing
                  the correct option from the four options given in each question.
                    1.  The area to be used for planting rose flowers is                                 Floriculture

                    3.  The earnings from roses are expected to be `10,000. The earnings from sunflowers are expected to be
                       three-fourths of this. The value of the earnings from sunflowers is
                        (a)  `6500              (b)  `7500               (c)  `5500               (d)  `9500
                    4.  What is the ratio of the earnings from roses to the earnings from sunflowers?

                    5.  She has planned to distribute 150 roses to 50 friends to celebrate her farming initiative. An equal
                       number of roses will be given to all the friends. If we write the number of roses to be given to each
                       person as a fraction, this fraction will be
                             3                       1                       3                        24
