Micheal , Saren and Donald decided to club together to buy a present. Each of them gave equal amount of money. Luckily Saren negotiated a 20% discount for the present so that each of them paid 4 dollars less. How much did they pay for a present? | [
"36",
"48",

We know that Saren negotiated a discount of 20%, so each of them paid $4 less.

They paid $12 less than the base price, so they spent $48. | AquaRat_train |

A train has a length of 150 meters . it is passing a man who is moving at 3 km/hr in the same direction of the train, in 3 seconds. Find out the speed of the train. | [
"169 km/hr",
"182 km/hr",
"183 km/hr",
"180 km/hr"
] | C | Explanation:
Length of the train, l = 150m
Speed of the man , Vm= 3 km/hr
Relative speed, Vr = total distance/time = (150/3) m/s = (150/3) × (18/5) = 180 km/hr
Relative Speed = Speed of train, Vt - Speed of man (As both are moving in the same direction)
