In a village there are 150 men and 90 women in present time.if in next year population will be P=(a^2 +b^2)^1/2 , and in every year men are reduces 5%.what is population of after 2 year. Choose the most appropriate option: A) 140 B) 141 C) 142 D) 143 E) 146
next year total population=[150^2+90^2]^.5=174.92=175   man decreased by 5% so total man =150*.95= 
<gadget id="calculator">150*.95</gadget>
<output>142.5</output>
142.5   women will be= 175-142.5= 
<gadget id="calculator">175-142.5</gadget>
<output>32.5</output>
32.5   so population after two years= [135^2+32.5^2]^.5=146.15=146   so population after two year= 146   ANSW146R:146
