two boys and a girl can do a work in 5 days, while a boy and 2 girls can do it in 6 days. if the boy is paid at the rate of $28 a week.,what should be the wages of the girls?


A.$12
B.$16
C.$23
D.$17
E.None

• 2b+1g=1/5=>10b+5g=1---------(1)
  1b+2g=1/6=>6b+12g=1---------(2)
  from (1)&(2)
  10b+5g=6b+12g
  4b=7g
  b:g=7:4
  but above ratio is reverse b:g=4:7
  wages of the girls=(4*28)/7
  =4*4=16

• B. $16
  
  Let the 1 day work of a boy=b and a girl=g, then
  2b + g = 1/5 ---(i) and
  b + 2g = 1/6 ---(ii)
  On solving (i) & (ii), b=7/90, g=2/45
  As payment of work will be in proportion to capacity of work and a boy is paid $28/week, so a girl will be paid 28*(2/45)/(7/90) = 16 $.

• 5(2b+1g)=6(1b+2g)
  4b=7g
  G=4/7g
  G=4/7 * 28
  G=16$ per week

• (2b+g)5=(b+2g)6
  4b=7g
  b/g=7/4
  ratio of their efficiency is b:g=7:4
  rate paid to boy is 28 i,e 7*4
  then for girl 4*4=16

• 2B+G-->1/5 .....(1)
  B+2G-->1/6 .....(2)
  By simplifying (1) & (2),
  ==>B : G
  7/90 : 2/45
  1/4 : 1/7
  1 : 4/7 ==>(4/7)*28 = 16
