Answer: C) 80% Explanation: circumference of A = 2πr = 8 => so r = 4πvolume = π×4π2×10 = 160πcircumference of B = 2πr   = 10 => so r = 5πvolume = π×5π2×8 =  200πso ratio of capacities = 160/200 = 0.8 so capacity of A will be 80% of the capacity of B.

Answer: C) IBM Explanation: A team of researchers at IBM has created the world’s smallest magnet using a single atom which can store one bit of data on it.

It is given that the first digit is 1/3 of the second. There are 3 such possibilities 1)1 and 32)2 and 63)3 and 9 Now, the third digit is the sum of the first and second digits.1)1 + 3 = 4 2)2 + 6 = 83)3 + 9 = 12It is clear that option 3 is not possible. So we are left with only two options. Also, the last digit is three times the second, which rules out the second option. Hence, the answer is 1349.

Answer: A) 20 Explanation: Let the runs scored by P, Q, R, S and T be  a, b, c, d and e From given data, a + b + c + d + e = 36 x 5 = 180b + c = 107Let a = xe = x-8d = x-3now 3x - 11 + 107 = 1803x = 84x = 28e's score = 28-8 = 20
