• # question_answer If 10 pears cost Rs.72, then how many pears can you buy if you have Rs. 36? A) 3                         B)        4 C) 5         D)        6 E) None of these

Explanation: Option (c) is correct. In Rs.72, the number of pears you can buy = 10 10 So, virtually in Rs. 1, the number of pears you can buy = $\frac{10}{72}$ Therefore, in Rs. 36, the number of pears you can buy = $\frac{10}{72}\times 36=\frac{10\times 36}{72}=10\times \frac{36}{72}$ =$10\times \left( \frac{36\div 36}{72\div 36} \right)=10\times \frac{1}{2}=\frac{10}{2}=5$ Rest of the options is incorrect because of the correctness of option (c).
