 (3) 5 minutes 17 seconds past 8 (4) 2 minutes 27 seconds past 8 
6. 1 
Sol. They will ring together again after L.C.M of (6, 12, 18, 24) seconds that means after 72 
seconds (or) one minute 12 seconds. 
 
7. A cricketer has a certain average of runs for his 64 innings. In his 65
th
 inning, he is bowled 
out for no score on his part. This brings down his average by 3 runs. His new average of 
runs is: 
 (1) 195  (2) 130 
 (3) 192 (4) 128 
7. 3 
Sol. Assume, the average upto 64 innings = x 
 So the score for 64 innings = 64x 
 Now the average after 65 innings = x – 3  
 ? Total score in 65 innings = 65 (x – 3) 
 From given data we have : 
 ? ? 64x 65 x 3 ? ? 
 64x = 65x – 65 (3) 
 x = 195 
 
8. If x 136 52 144 ? ? ? then value of x equals:

15. How many numbers between 11 and 90 are divisible by 7? 
 (1) 10 (2) 11 
 (3) 12 (4) 7 
15. 2 
Sol. Divisible by ‘7’ means the number = 7k (for k = 1, 2, 3 …) 
 Now between 11 and 90 means 
 K = 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 
 Total values = 11 
 
16. Given that 2x – y + z = 240. If z = 2y, y = 2x, then x = ? 
 (1) 0 (2) 50 
 (3) 70 (4) 60 
16. 4 
Sol. z = 27 
 y = 2x 
 ? z = 2 (2x) = 4x 
 2x – y + z = 240 
 2x – 2x + 4x = 240 
 4x = 240 
 X = 60.

7. A cricketer has a certain average of runs for his 64 innings. In his 65
th
 inning, he is bowled 
out for no score on his part. This brings down his average by 3 runs. His new average of 
runs is: 
 (1) 195  (2) 130 
 (3) 192 (4) 128 
7. 3 
Sol. Assume, the average upto 64 innings = x 
 So the score for 64 innings = 64x 
 Now the average after 65 innings = x – 3  
 ? Total score in 65 innings = 65 (x – 3) 
 From given data we have : 
 ? ? 64x 65 x 3 ? ? 
 64x = 65x – 65 (3) 
 x = 195
