    DIRECTIONS: Below are given some symbols indicating some relations given against them Read these symbols carefully and then answer the questions given below. There are four options to each question, of which only one is correct. Find the correct answer. \[\Delta =\]greater than;          \[+=\]not greater than \[\theta =\] equal to;               \[\phi =\]not equal to \[\times =\] less than,              \[\square \,=\]not less than \[c+b\times a\]means

    A)  \[a\times b\,\theta \,c\]            

    B)  \[c\,\Delta \,b\,\Delta \,a\]

    C)  \[c\times b\times a\]               

    D)  \[b\,\theta \,c\,\square \,a\]

    Correct Answer: B

    Solution :

        With the notations given, \[c+b\times a\] means \[c\le b<a\] From option (a), \[a\times b\,\theta \,c\] means \[a<b=c,\] this is not true. From option (b), \[c\,\Delta \,b\,\Delta \,a\] means \[a>b>c,\] this is true. From option (c), \[c\times b\times a\] means \[a<b<c,\]this is not true. From option (d), \[b\,\theta \,c\,\Delta \,a\] means \[b=c>a,\]this is not true.
