1.If 'L' stands for '+', 'M' stands for '-' , 'N' stands 'x' , 'P' stands for '/',then 14 N 10 L 42 P 2 M 8= ? A) 153 B) 216 C) 248 D) 251 View Answer Report DiscussAnswer: Option AExplanation:Given expression = 14 x 10 + 42 / 2 - 8 = 14 x 10 + 21 - 8 = 140 + 21 - 8 = 161 - 8 =153
2. A) 18 C 3 D 6 B 8 C 4 G 12 B) 18 A 3 E 6 B 8 G 4 B 12 C) 18 C 3 G 6 B 8 B 4 D 12 D) 18 F 3 B 6 E 8 G 4 E 12 View Answer Report DiscussAnswer: Option CExplanation:18 / 3 - 6 + 8 + 4 =12 or 6- 6 +8+4=12 or 12=12
3.If 'x' stands for 'addition', '<' for 'substraction' , '+' for 'division' ,'>' for 'multiplication', '-' for 'equal to' ,'/' for 'greater than' , then state which of the following is true A) 3 x 4 > 2 - 9 + 3 < 3 B) 5 x 3 < 7 / 8 + 4 x 1 C) 5 > 2 + 2 = 10 < 4 x 8 D) 3 x 2 < 4 / 16 > 2 + 4 View Answer Report DiscussAnswer: Option CExplanation:5 x 2 / 2 < 10 - 4 + 8 or 5 x 1 < 18 - 4 or 5< 14
4.If 'when' means 'x', 'you' means '/' ,'come' means '-' and 'will' means '+' ,then what will be the value of "8 when 12 will 16 you 2 come 10"? A) 45 B) 94 C) 96 D) 112 E) None of these View Answer Report DiscussAnswer: Option BExplanation:given Expression = 8 x 12 + 16 / 2 - 10 = 96 + 8 - 10 = 104 - 10 = 94
5.If Q means 'add to' , J means 'multiply by', T means 'subtract from' and K means 'divide by' ,then 30 K 2 Q 3 J 6 T 5=? A) 18 B) 28 C) 31 D) 103 E) None of these View Answer Report DiscussAnswer: Option BExplanation:Given expression = 30 / 2 + 3 x 6 - 5 = 15 + 18 - 5 =28
