If A, B, C are the mechanisms used separately to reduce the wastage of fuel by 30%, 40%, 10%.

What will be the fuel economy if they were used combine?

1.68.4          2.62.2         3.58         4.27

My flight takes of at 2pm from a place at 18N 40E and landed 10 Hrs later at a place with coordinates 36N40W.

What is the local time when my plane landed?

The number 384 in decimal system is given by (1432) x in the X System of numbers find the value of X

a) 5 b) 6 c) 7 d) 8 e) 9

Ans: a)

What is the unit of the following?       (power*time) / (velocity*velocity)

1.mass    2.distance            3.velocity           4.speed

Ans: mass                     Approach:     power=work/time

hence numerator=(work*time)/time=work

work=Force*distance

Force=mass*acceleration

accelaration=distance/time^2

now numerator is (mass*distance^2) / (time^2)

denominator is (distance^2) / (time^2)       since velocity=distance/time
