Total wages = Rs. 4800
Person A-5
Person B-8
One day’s work = A-1/5
&
B-1/8
With help of a Girl and a boy
1/5 + 1/8 + 1/(G+B) = 1/3
13/45 + 1/(G+B) = 1/3
1/(G+B) = 2/45
1/5:1/8:2/45=1/3
Wages of girl + boy =3x2/45x4800 = 320x2=640
Boy -8
Girl -2B
G+B=640
2B+B=640
3B=640
B=640/3= 213.3
Therefore, the wages of girl is -213.3x 2= Rs.426.7.
