Question

In a certain code, '253' means 'books are old'; '546' means 'man is old' and '378' means 'buy good books'. What stands for 'are' in that code?

• A. 4
• B. 2
• C. 5
• D. 6

Answer 1

The correct option is B 2

Given: 'Books are old" ${\equiv }^{\prime }{253}^{\prime }.....\left(i\right)$
'Man is old' ${\equiv }^{\prime }{546}^{\prime }.....\left(ii\right)$
'Buy good books' ${\equiv }^{\prime }{378}^{\prime }......\left(iii\right)$
From equations (i) and (ii),
'old' is coded as '5'.
From equations (i) and (iii),
'books' is coded as '3'.
From equation (i),
'are' is coded as '2'.

Hence the answer is option B
