Answer: D) 8 Explanation: Here the given number analogy follows two patterns that, 6  18 --> 6 x 3 4 12 --> 4 x 3   OR 6 18 ----> 6x6/2 = 18 4 8 ----> 4x4/2 = 8   As 12 is not available in the options, 8 is correct answer.

Answer: B) 13.63% Explanation: Required % is given by    => 12100-12x100   = 1200/88   = 13.636%

The rule followed here is 7 + 3 - 4 = 6 Similarly, 4 + 2 - 2 = 4 9 + 5 - 4 = 10 Hence, the missing numbers are 4 & 10.

Answer: B) Rs. 441 Explanation: Given principal amount = Rs. 8000 Time = 3yrs Rate = 5% C.I for 3 yrs = 8000 x 105100 x 105100 x 105100 - 8000= Rs. 1261   Now, C.I for 2 yrs = 8000 x 105100 x 105100= Rs. 820    Hence, the required difference in C.I is 1261 - 820 = Rs. 441

There are many possibilities for this. We can hold a breathe, meeting, conversation, party, grudge, etc... but cannot touch them.

Answer: C) forest improving to deserts Explanation: Desertification is a type of land degradation in which a relatively dry area of land becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlife.   Conversion of a grassland or an already arid land into a desert through indiscriminate human actions magnified by droughts.   Hence, forest improving to deserts is refers to desertification.

Answer: B) 2 : 1 Explanation: Given that train K crosses a pole in 30 seconds and train L crosses the same pole in one minute and 15 seconds. Let the length of train K be Lk and that of train L be Ll given that Lk = 3/4 Ll As the train K and L crosses the pole in 30 seconds and 80 seconds respectively, => Speed of train K = sk = Lk/30 Speed of train L = sl = Ll/80 Lk = 3/4 Ll => sk = 3/4 Ll/(30) = Ll/40 Ratio of their speeds = sk : sl = Ll/40 : Ll/80 => 1/40 : 1/80  =  2 : 1

Answer: C) 3:4 Explanation:
