### Question

In a certain code language 'faster calculations math methods' means '245 591 573 168', 'calculations without calculator needed' means '671 281 246 573', 'shortcut techniques analytical methods' means '853 169 591 742' and 'calculator not nice tool' means '671 735 865 734'. Then what is the code for 'calculations methods'?

A

573 591

B

169 742

C

281 671

D

168 734

Soln.
Ans: a

'573' is common to items 1 and 2. So '573' = 'calculations'. Next we can see that '591' is common to items 1 and 3. So '591' = 'methods'. Hence 'calculations methods' should be '573 591' or '591 573'
