The cost of 16 packets of salt, each weighing 900 grams is 28. What will be the cost of 27 packets, if each packet weighs 1 kg?

(A) 52.5
(B) 56
(C) 58.5
(D) 64.75
(E) 65
Use the work-rate concept discussed here: https://anaprep.com/arithmetic-work-rat ... variation/

16 packets ................. 900 Gms ............... 28
27 packets ................. 1 kg ...................... ??

\(Cost = 28 * \frac{27}{16} * \frac{1}{0.9} = 52.5 \)

Answer (A)
