20 people going to one temple. (some time waste data) They want Rs. 20. For men-Rs.3, women-Rs.2, children-50 paisa. How much money spends for men, children and women?

• we cannot solve for three variables using two equations

• Rs.3,Rs.7,Rs.10
  
  Let number of men be x, women y and children z
  
  x+y+z = 20 ---(1)
  
  men gives 3 rupees each --->total money spend by men = 3x
  women gives 2 rupees each--->total money spend by women =2y
  children gives 50 paisa each ---> total money spend by children = 0.5z
  Total 20 rupees is given by all
  
  3x+2y+0.5z = 20 ---(2)
  
  Solving (1) and (2)
  x=1 , y=5 , z = 14
  
  total money spend by men = 3x = Rs3
  total money spend by women =2y = 2*5 = Rs10
  total money spend by children = 0.5z = 0.5*14 = Rs7

• 
  M=1 => 1*3= 3
  W=5 => 5*2= 10
  C=14 => 14*.5= 7
  
  1+5+14= 20 & 3+10+7=20

• x+y+z=20
  3x+2y+0.5z=20
  now verify it from option

• Ann Theressa , plz explain how did u solve the value of 3 unknowns using 2 equations?????

  by trail and error method.
  
  the 2 equations are
  
  x+y+z = 20 ---(1)
  and
  3x+2y+0.5z = 20 ---(2)
  
  multiply eqn (1) by 2
  
  2x+2y+2z = 40 ---(3)
  
  eqn (3) - (2) gives
  
  -x + 3/2*z = 20
  3/2 *z = 20 + x
  
  Since x,y and z are positive numbers,from this equation 3/2*Z must be greater than 20.(z > 13)
  
  From equation (1) z is less than or equal to 18.(min value of x and y can be 1)
  Also from equation (2) , z must be an even number.
  
  So z can be 14,16 or 18
  Lets take z = 14
  
  3/2*z = 20+x
  x = 1
  x+y+z = 20
  so y = 5
  
  Substituting these values in eqn (2)
  3x + 2y + 0.5z = 3+10+7 = 20
  which satisfies both the equations.

• its a random methodology.
  since fr women rs 2 it is even .so rs fr men and child to be odd so tat total 20rs is even.
  choose appropriately u vl get answer within 3 possible inputs

• 0.5*14=7 3*3=9 2*3=6 men 3 women 3 children 14 total 20 rs 20

• a) Rs.6-men, Rs.4-children, Rs.10- women
  
  b)Rs.3-men, Rs.7-children, Rs.10- women
  
  c)Rs.3-men, Rs.8-children, Rs.9- women
  
  d)Rs.9-men, Rs.3-children, Rs.8- women
  
  Sol: By using options we calculate it easily.
  From option b
  Men - 1men*Rs.3= Rs.3
  Children - 14children* 50paisa= Rs.7
  Women - 5women*Rs.2= Rs.10
