    A) Rs. 37.50                      

    B)  Rs. 40

    C)  Rs. 35.20                     

    D)  Rs. 80

    Correct Answer: B

    Solution :

    Each worked for 3 h. Sunita's work for 3 h\[=3\times \frac{1}{6}=\frac{1}{2}\] So, Sunita gets \[\left( \frac{1}{2}\times 320 \right)\]=Rs. 160 Kavita's work for 3 h\[=3\times \frac{1}{8}=\frac{3}{8}\] So, Kavita gets \[\left( \frac{3}{8}\times 320 \right)\]= Rs. 120 Geetanjali gets \[=320-(160+120)\] \[=320-280\]Rs. 40
