Because he’s taxed by his home planet, Mork pays a tax rate of 10% on his income, while Mindy pays a rate of 20% on hers. If Mindy earned 3 times as much as Mork did, what was their combined tax rate? | [
"37.5%",
"36%",
"20%",
"17.5%"
] | D | Say Morks income is - 100
So tax paid will be 10
Say Mindys income is 3*100 = 300
So tax paid is 20% * 300 = 60
Total tax paid = 10+60 = 70.
Combined tax % will be 70/100+300 = 15.5% | AquaRat_train |

A man has Rs. 480 in the denominations of one-rupee notes, five-rupee notes and ten rupee notes. The number of notes of each denomination is equal. What is the total number of notes that he has? | [
"45",
"95",
"75",

Then x + 5x + 10x = 480
16x = 480
x = 30.
Hence, total number of notes = 3x = 90

A thief steals at a car at 3.30 p.m. and drives it at 60 km/hr. The theft is discovered at 3 p.m. and the owner sets off in another car at 75 km/hr. When will he overtake the thief? | [
"1 p.m",
"6 p.m",
"4 p.m",
"5 p.m"
] | B | E
6 p.m
Suppose the thief is overtaken x hrs after 3.30 p.m.
Then, distance covered by the owner in (x - 1/2) hrs.
60x = 75(x - 1/2) => x = 5/2 hrs.
So, the thief is overtaken at 6 p.m. | AquaRat_train |

What happens to temperature in the troposphere as the altitude increases? | [
"it increases",

] | B | In the troposphere, temperature decreases with altitude. The troposphere gets some of its heat directly from the Sun. Most, however, comes from Earth's surface. The surface is heated by the Sun. Some of that heat radiates back into the air. This makes the temperature higher near the surface than at higher altitudes. | SCiQ_train |
