A spider climbed 62 1 % 2
of the height of the pole in one hour and in the next hour it covered12 1 % of the remaining height. 2
If pole’s height is 192 m, then distance climbed in second hour is
-
- 3 m
- 5 m
- 7 m
- 9 m
Correct Option: D
Remaining height
| = |  | 192 - | % of 192 |  | 100 |
= 192 – 120 = 72 m
∴ Required distance (distance covered in second hour) then,
| = | % of 72 | 2 |
| = | = 9 m | 2 × 100 |
