The area of a circle is added to its diameter, and the circumference is then subtracted from this total, the result is 10. What is the radius of the circle? | [
"4",
"pi",
"2",
"2*pi"
] | A | The equation is; diameter + Area - Circumference = d + A - C = d + pi * r^2 - 2 * pi * r = 2r + pi * r(r - 2).
By plugging in the answers we can test the answers quickly; then, 4 is the only possible answer.

Two trains are moving in opposite directions at 60 km/hr and 90 km/hr. Their lengths are 1.10 km and 0.65 km respectively. The time taken by the slower train to cross the faster train in seconds is? | [
"48",
"11",
"99",
"42"
] | D | Relative speed = 60 + 90 = 150 km/hr.
= 150 * 5/18 = 125/3 m/sec.
Distance covered = 1.10 + 0.65 = 1.75 km = 1750 m.
Required time = 1750 * 3/125 = 42 sec.

If all the fractions 3/10, 1/16, 4/11, 2/9, 1/7, 5/14 and 5/24 arranged in descending order of their values, then which one will be the third? | [
"3/14",
"3/17",
"3/10",
"2/10"
] | C | Explanation:
3/10 = 0.3, 1/16 = 0.0625, 4/11 = 0.36, 2/9 = 0.22, 1/7 = 0.14, 5/14 = 0.36 and 5/24 = 0.21
4/11 > 5/14 > 3/10 > 2/9 > 5/24 > 1/7 > 1/16
3/10 will be the third.
