Given :-50 men do 10 hours work daily complete work in 20 days80 men do job in 50% timeTo Find :-Days requiredSolution :-1 man may do job in (50 × 20) days =1 man may do job in 1000 days

Now,

80 man = 1000/80 = 12.5

Now,

When hours reduced 50% then we will multiply days by 2Total days = 12.5 × 2 = 25 days.HenceOption C is correct

Step-by-step explanation:

Right triangle ABC is reflected over AC to form triangle AFC.

Triangle AFC dilated by a scale factor of two-thirds to form triangle DEC.

Reflection is a rigid transformation which preserves lengths and angles, then

Dilation is a transformation which maps the triangle into similar triangle, so

Thus,

Similar triangle have congruent corresponding angles, so

and proportional corresponding sides

Thus, correct options are:
