A certain number of trucks required to transport 60 tons of steel from TISCO to Jamshedpur
However it is found that since each truck could take 0.5 tons of cargo less. Another 4 trucks were needed. How many trucks initially planned to use ?
10
15
20
25
==========================
n = no of truck
n = no of truck
t = capacity of each truck to carry
n*( t + 0.5) = 60 ---- (1)
(n+4) * t = 60 ---- (2)
solving the equation
solving the equation
n = 8t
putting in equation
putting in equation
8t^2 + 4t -15 = 0
t = 5, -6
Thus
n = 40 : but OA = 20
t = 5, -6
Thus
n = 40 : but OA = 20

Two Astronauts, Vaibhav and Kanishk land on a spherical shaped meteor of diameter 7 km, which is rotating about its own central axis at 2.5 km/sec. Equator is the maximum circumference possible on the spherical shaped meteor. Vaibhav starts running along the equator at 20% of the speed of the meteor in a direction opposite to the direction of the rotation of meteor. Kanishk standing at the point from Vaibhav started, records the time taken by Vaibhav to reach the starting point once again. Calculate the time recorded by Kanishk.
a 44 sec
b 12 sec
c 48 sec
d 11 sec
e 22 sec
