There are 8436 steel balls, each with a radius of 1 cm, stacked in a pile, with 1 ball on top, 3 balls in the second layer, 6 in the third layer, 10 in the fourth and so on. the number of horizontal layer on the pile is
A. 34 B. 38 C. 36 D. 32 E. None
C. 36
Explanation : Assume the number of layers in horizontal pile is n. So, Σn(n+1)/2 = 8436. => (1/2) [ Σn2 + Σn ] = 8436. => n(n+1)(n+2)/12 +n(n+1)/4 = 8436. => n(n +1) [(2n + 4) / 12 ] = 8436. => n(n +1)(n+2) / 6 = 8436. => n(n +1)(n+2) = 36 x 37 x 38. So, n=36. Answer : C

B. 9 3/4% stock at 117
Let investment in each case be Rs. (143 x 117). Income in 1st case = Rs. 11 x 143 x 117 = Rs. 1287. 143 Income in 2nd case = Rs. 39 x 143 x 117 = Rs. 1394.25 4 x 117 Clearly, 9 3 % stock at 117 is better. 4 Answer:B

The lunar landscape is covered by craters caused by what? A. earth impacts B. water C. volcanoes D. asteroid impacts
D. asteroid impacts
The landscape of the Moon - its surface features - is very different from Earth. The lunar landscape is covered by craters caused by asteroid impacts ( Figure below ). The craters are bowl-shaped basins on the Moon’s surface. Because the Moon has no water, wind, or weather, the craters remain unchanged.
