Answers :
1) Answer: A
The pattern is as follows:
2985984/12 = 248832
248832/12 = 20736
20736/12 = 1728
1728/12 = 144
144/12 = 12
2) Answer: D
The pattern is as follows:
192+30=391
242+35=611
292+ 40 = 881
342Â + 45 = 1201
392Â + 50 = 1571
442Â + 55 = 1991
3) Answer: E
The pattern is as follows:
8*5+1=41
9*6+1=55
10 * 7 +1=71
11*8+ 1=89
12 * 9+ 1= 109
13 * 10+1=131
4) Answer: C
The pattern is as follows:
64 * 2.5 = 160
160 * 3.5 = 560
560 * 4.5 = 2520
2520 * 5.5 = 13860
13860 * 6.5 = 90090
5) Answer: C

x =6
Speed of the stream=6 * 2=12 kmph
