24,45,63 find the hcf of the following group of number using the method of division by common factor

Answer:

Essentially, Science and Technology have introduced us to the establishment of modern civilization. This development contributes greatly to almost every aspect of our daily life. Hence, people get the chance to enjoy these results, which make our lives more relaxed and pleasurable.

Answer:Transport needs in the coming years will be growing. Strong emphasis will have to be placed on servicing new patterns of trade and on meeting the requirements of increased activities in agriculture. Expenditures for transport will be large.

In dealing with transport, subject areas are the various modes, the two elements, infrastructure and equipment, and a range of interdependent items including development and construction, operation and maintenance.

The magnitude and complexity of forthcoming transport needs will call for application of powerful and efficient methodologies. Tools of the past will not be sufficient. Skills derived from the current state of science and technology are available and they will have to be used.

Potential applications of science and technology are numerous. Foremost areas so far as infrastructures are concerned are conceptual orientation methods, modelling techniques, various tools for engineering investigations and controlled construction. As far as equipment is concerned, they include materials, tools, expertise and off-the-shelf components. Useful items are available for development, operation and maintenance of transport in all modes.

Some aspects of transport are nevertheless neglected. Science and technology could beneficially target the field of intermediate transport technologies to suit the needs of developing countries and the field of energy where reduced consumption, cheaper energy and cheaper transport techniques should be sought.

Science and technology predominantly yield effective but sophisticated solutions. The use of these solutions in developing countries introduces a risk of increased dependence on the developed world. This risk should however be viewed against the advantages of accelerated social and economic development. Proper planning is clearly of the essence.

Science and technology provide a wide range of conceptual, methodological and implementation tools, including tools for eliminating prevailing gaps. Programmes are required to identify priorities, mobilize resources and proceed with action.

(a) Since, the highest central angle is 120

0

 is of the bus

hence, the most common mode of transport is the bus.

(b) Fraction of children traveling by car =

total angle

(c) No. of children traveling by car  = Fraction of children traveling by car× Total no of children.

⇒18=

× Total no of children...... from (b)

⇒ Total no of children  = 18×4

⇒ Total no of children = 72

(d) Central angle of children who do not take taxi = 120

(e) The central angle for students traveling by cycle and those who walk is the same.

Thus, the two modes of transport are an equal number of children traveling are cycle and walking.
