    B)  30      

    C)  50                  

    D)         20      

    Correct Answer: C

    Solution :

    Cost of one cycle = Rs. 525 \[\therefore \] Cost of 52 cycles                         \[\text{=Rs}\text{. 525 }\!\!\times\!\!\text{ 52=Rs}\text{. 27300}\] New cost of one cycle                         \[\text{=Rs}\text{. (525+21)=Rs}\text{. 546}\] So, number of cycles bought with Rs. 27300 \[\text{=}\frac{27300}{546}=50\]
