A cistern of capacity 8000 litres measures externally 3.3 m by 2.6 m by 1.4 m and its walls are 5 cm thick. The thickness of the bottom is: | [
"90 cm",
"4 dm",
"1 m",
"None of these"
] | B | Explanation:
Let the thickness of the bottom be x cm.
Then , [(330 - 10) × (260 - 10) × (140 - x)] = 8000 × 1000
=> 320 × 250 × (140 - x) = 8000 × 1000
=> (140 - x) = 8000×1000/320=
100
=> x = 40 cm = 4 dm.

In January of 2016, there were 100 cats and 125 dogs in a town. In January of 2017, there were 115 cats and 150 dogs. By approximately what percent did the ratio of cats to dog decrease from the 2016 to 2017. | [
"5%",
"12.9%",
"18%",
"11.0%"
] | B | 2016: cats/dogs = 100/125 =660/750
2017: cats/dogs = 115/150 =575/750
ASIDE: It's useful to write both ratios with the same denominator. This allows us to IGNORE the denominator and focus solely on the numerators.
So, our ratio went from 660/750 to 575/750
Ignoring the denominators, we went from 660 to 575
