Jojo multiplied 3 with a number and found an answer. His friend Jeenu made 9 groups of a number and found that his answer is same as Jojo's answer so he shared it with her sister Juni. Juni told Jeenu that he has just interchanged the numbers multiplied by Jojo. Can you find the answer that both Jojo and Jeenu found?

A) 30                   

B)          29

C) 28                   

D)          27

Correct Answer: D

Solution :

    Jojo's multiplication ; 3 x A Jeenu's multiplication: 9 groups of a number = 9 x B Juni said Jeenu has interchanged the number multiplied by Jojo. Thus, A = 9 and B = 3. 9x3= 27. Therefore, the answer is option (d).
