Question:

A sum of Rs, 2156 was to be divided among P, Q, R, and S in the ratio of 2 : 3 : 4 : 5 but it was divided in the ratio of \(\frac{1}{2}\) : \(\frac{1}{3}\) : \(\frac{1}{4}\) : \(\frac{1}{5}\)

Options:

P received 534 more

Q received 90 more

R received 196 less

S received 440 less

Correct Answer:

R received 196 less

Explanation:

(1)       P           :          Q        :       R        :         S    

 \(\frac{1}{2}\) : \(\frac{1}{3}\)  :  \(\frac{1}{4}\)  :  \(\frac{1}{5}\)   

multiply with 60 (LCM of 2, 3, 4, 5)

               P           :          Q        :        R       :         S

              30          :          20      :        15      :        12

2156 in    2          :            3       :         4      :           5

(right)    308                   462              616              770

2156 in   30         :            20      :        15    :           12

(wrong)   840                   560             420               336
